ArchDaily x Open House: The Latest Architecture and News

In the heart of Tallinn, where history weaves through cobblestone streets and ancient towers, stands the Ungern-Sternberg Palace — a monument that bridges the opulent past of Estonia's aristocracy with the vibrant world of contemporary academia. Now home to the Estonian Academy of Sciences, this historic building embodies Estonia's enduring dedication to knowledge and cultural preservation. Through Open House Tallinn, which highlights the city's architectural heritage, the palace's significant history, and remarkable architectural details are brought to a wider audience, offering unique insight into Estonia's cultural resilience.

Constructed in the 19th century as a symbol of aristocratic power, the palace has transformed from a private residence into a national hub of intellectual life. Its grand halls, once the scene of lavish gatherings, now foster scientific and academic pursuits, illustrating how heritage architecture can evolve alongside societal change.

Standing out among the array of cultural programs, the opera and theater typology is often understood as encompassing the luxurious and elitist spirit of a bourgeois society focused on entertainment. Across the Soviet Union, this represented the opposite of the principles to be promoted. However, despite the opposition of the political class, the program remained widely popular. As the historical structures, symbols of the previous regime could no longer be promoted, the search began for a new image of the Opera House, one aligned with Socialist ideals and the concept of "art belonging to the masses."

This is the case of Soviet Lithuania, which, in the 1940s, began the process of developing a new Opera and Ballet Theater in Vilnius to replace the theatre in Pohulianka. The process resulted in an unusual commission, as young architect Elena Nijolė Bučiūtė won the 1960s competition for architectural design, turning the initial socialist realist proposals into a welcoming and expressive design, blending elements of early and late modernism. This also represents a surprising accomplishment for a young architect who was a woman and not a member of the Communist Party. The project is featured in the program of Open House Vilnius, focused on the theme "People who create the city."

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.

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.

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. A total of 58 locations will be available to visitors, exploring a variety of programs and scales demonstrating
