Integrating contemporary art with the landscape in a dialogue between human creation and the natural environment, the Sculpture Space of the National Autonomous University of Mexico (UNAM) represents one of the most important public artworks in Latin America. Both the Sculpture Space and the Pedregal de San Ángel Ecological Reserve at UNAM in Mexico City have recently been awarded the Carlo Scarpa International Prize for Gardens 2023-2024, granted by the Benetton Foundation for Studies and Research based in Treviso, Italy. They were recognized for their high natural, historical, and cultural value as works of preservation and collective art that emerged from a lava surface where new neighborhoods and UNAM’s University City were developed.
In the south of France, a 40-minute drive east of Montpellier, lies the otherworldly resort town of La Grande Motte. Named after a nearby sand dune, the city is characterized by futuristic, pyramid-shaped apartment blocks in various relief forms, adorned with diverse vegetation including pines, planes, olives, poplars, and cypresses. Artists Charly Broyez and Laurent Kronental describe this unique character as "a fairy-tale vision of a land emerging from the uncharted territories of our psyche, loaded with memories, images, sounds, colors, history." Through their meticulous images, they reveal the city's distinctive architecture.
At the turn of the millennium, the world was gripped by the looming threat of the Y2K bug, a potential failure of computerized systems that could disrupt everything from banking to aviation. As midnight approached on December 31, 1999, people withdrew their savings, major corporations issued warnings, and governments scrambled to prevent public hysteria. But as the sun rose on January 1, 2000, the feared bug had no material impact, and the crisis faded as quickly as it had emerged. However, this era left its mark in unexpected places — particularly in architecture. Amid the anxiety surrounding digital technology, one of the most iconic concert halls of our time, Casa da Música in Porto, was born. Designed by OMA (Office for Metropolitan Architecture), its origins can be traced to a much smaller project: the Y2K House. What began as an exploration of private domesticity during the digital scare evolved into a grand public structure — an architectural transition from home to a performance hall.
Greenways, as a typology of urban design, have become an essential element in the planning of modern cities. They emerge in response to the increasing fragmentation of urban landscapes by elements such as highways. They usually integrate natural and constructed spaces, providing much-needed connections across various parts of the city. At the same time, they promote pedestrian accessibility, recreation, and social interaction. The Rose Kennedy Greenway in downtown Boston, United States, exemplifies this human-centered approach to design. The project, which began construction in 1991, showcases the potential of greenways to reconnect urban environments and enhance community life. As a series of parks designed by various architecture firms, it aims to create physical links and meaningful spaces that foster social development and a sense of place.
Tegucigalpa, the capital of Honduras, offers a dynamic blend of the country's architectural heritage with mountainous landscapes. Nonetheless, just like many other cities in Latin America, it faces significant urban challenges such as social class disparities and a fragmented urban fabric. In response, several design initiatives have emerged over the years to address those issues. One of the most prominent examples is the "Villa for Girls", designed by the Guatemalan firm Solis Colomer Arquitectos, which has now expanded to include a "Villa for Boys" since 2017. These projects are aimed at children from low-income families who often face the risk of being recruited by gangs. Together they build upon an architectural legacy that offers a safe, supportive environment to grow and learn.
From 1977 to 1983, the National Theatre in Prague underwent a major transformation with the opening of Nová Scéna, a modern counterpart to the traditional Neo-Renaissance theatre. For many years, Nová Scéna hosted the renowned Laterna Magika, the world’s first multimedia theatre. This groundbreaking performance style combined classical theatre with computer-generated visual effects, creating a unique dramatic experience. The striking glass building, a symbol of the communist era, became an iconic representation of the political power of the time.
Gyumri, the capital of Armenia's Shirak region and the country's second-largest city, was historically known for its culture and architectural heritage. While it was part of the Soviet Union, the city hosted many factories that turned it into a primary industrial center in the region, reaching a population of approximately 225,000 people. However, during the past decades, Gyumri has seen a considerable population decline as a consequence of a devastating earthquake that destroyed the city in 1988 and killed thousands of people. More than 30 years later, Gyumri's regeneration process is still unfolding. The city's ongoing efforts to restore its built environment and boost economic development offer valuable insights into how urban regeneration can be navigated in the aftermath of disaster.
As record-breaking temperatures sweep across European cities, practitioners have recognized that existing infrastructure is poorly equipped to address the impacts of climate change. In response to this concern Roofscapes, a startup emerging from the MIT School of Architecture and Planning, has developed innovative solutions to amplify urban climate resilience. Their approach focuses on the strategic adaptation of underutilized spaces such as rooftops. By tackling the immediate challenges posed by extreme heat, the startup's work epitomizes how architectural innovation can directly contribute to addressing climate adaptation needs in cities. The company was recognized as one of ArchDaily's 2024 Best New Practices for their innovative approach to tackling urban issues such as affordability, lack of biodiversity, rising urban temperatures and repurposing.
As a landmark of contemporary religious architecture in Portugal, the Church of the Sacred Heart of Jesus stands in contrast to traditional models, representing a work free from historicist stigmas. Resulting from a design competition organized in 1960, the church is notable for its civic dimension, urban role, and its anti-monumental and social significance. Integrated into the regular grid of the Avenidas Novas neighborhood, this example of the Movement for the Renewal of Sacred Art is part of a larger parish complex that often goes unnoticed by passersby. Its external street creates an unexpected public space, inviting people to enter and engage in a courtyard where architecture and the city merge. Finely crafted in terms of spatiality, detail, and light, the church holds many surprises for those who venture inside.
Cheongye Stream, known as Cheonggyecheon (청계천) in Korean, runs eastward through the heart of Seoul, passing through 13 neighborhoods in four districts of the capital of South Korea. Throughout its history, the stream played different roles in the city until it was covered by an elevated highway in the 1970s. For over 30 years, this natural artery remained hidden. It was not until 2003 that the city government launched a restoration project to reintegrate this urban waterway into the city fabric, revitalize the local economy, and revive the area's history and culture. The revitalization efforts were led by Mikyoung Kim Design. Since the project's completion in 2005, it quickly became one of Seoul's most visited tourist attractions. Moreover, it has become a focal point for ample urban research, with many studies offering positive assessments of the impact it had on Seoul's urban, economic, and ecological context.

Studio Ghibli and its co-founder Hayao Miyazaki have become household names in the West, thanks to their impressive body of work, which includes over 10 feature films, 2 Oscars, and more than 100 awards worldwide. Films such as "Spirited Away" and "Howl's Moving Castle" showcase their mastery of world-building, story telling and compelling visuals which have earned them global acclaim. This has created a devoted fan base that previously only had the Studio Ghibli Museum in Tokyo to experience the films in real life. As the studio's popularity and movie portfolio grew, it became inevitable for them to expand into a larger space. That is why November 2022 marked the beginning of a new phase as the Ghibli Park opened its gates in Nagoya, Japan.
Located north of Dakar, near the city's airport, is an architectural composition of triangular volumes known as the International Trade Fair Centre, Dakar, Senegal. Also known as the Foire Internationale de Dakar or FIDAK, this structure is an iconic example of 60s modernism in West Africa. It synthesizes the complexity of simple forms within vernacular spatial patterns. Completed in 1974, it reflects the post-colonial ambition of the country and has grown as an adaptive spatial framework for major cultural events and exhibitions.
The landmark of Piraeus, located in the heart of the largest passenger port in Europe, began construction in 1972 but remained unfinished and vacant for decades. Finally completed in 2023, after an international competition, it now stands as Greece's first green and digital skyscraper. The architectural firm PILA took on the design of the facades, while the office ASPA-KST designed the commercial spaces, and the new general architectural study was entrusted to Betaplan. After over four years of renovation, Piraeus Tower officially opened its doors to tenants and visitors on June 4th with a night of celebrations, establishing itself as a bustling hub and injecting vitality into the area.
Around 1949, the city of Buenos Aires led the construction of the Sixth Pantheon in the Chacarita neighborhood. Monumental in character and brutalist in style, this underground necropolis turned out to be the first and largest experiment in modern architecture in the funerary field. Designed by Ítala Fulvia Villa, one of the first Argentine women architects and urban planners, and a pioneer of South American modernism, along with her team comprised of Leila Cornell, Raquel S. de Días, Gunter Ernest, Carlos A. Gabutti, Ludovico Koppman, and Clorindo Testa, this work was discovered by Léa Namer, who conducted an in-depth investigation reflecting on the legacy of a modern utopia and a feminist rereading of history.
In response to the Czech Republic's soaring real estate prices, architecture firm KOGAA has transformed a former storage facility in Brno into DADA Distrikt, an affordable and diverse housing development. The project's economic approach, achieved through shared funding and direct sales, bypasses extra costs associated with developers while refurbishing a part of the city’s industrial heritage, transforming it into an active urban district. The project also features sustainability measures aimed at lowering its maintenance costs, further exemplifying the intersection of affordable housing, heritage restoration, and sustainable urban living.
The project is now part of Open House Brno, a free weekend festival held annually that allows visitors to enter and explore various locations across the city and discover their stories and architectural narratives. This year, the festival follows the curatorial concept of “Inclusion and Accessibility”, showcasing barrier-free integration of urban locations and the societal impact of buildings.
