Historically, "cyclopean" referred to a building technique that superimposed large stone blocks together without any mortar. This allowed for a diverse array of structures across various civilizations, including defensive walls, talayots, navetas, nuraghes, temples, tombs, and forts. Nowadays, the term applies to any ancient structure consisting of large stones superimposed to form a polygonal shape.

Yuval Noah Harari points out that, around 300 thousand years ago, Homo erectus, Neanderthals, and ancestors of Homo sapiens already used fire daily. According to the author of the international bestseller “Sapiens,” fire created the first significant gap between man and other animals. "By domesticating fire, humans gained control of an obedient and potentially limitless force." Some scholars even believe that there is a direct relationship between the advent of the habit of cooking food (possibly due to the domestication of fire) and the shortening of the intestinal tract and growth of the human brain, which allowed human beings to develop and create everything we now have.

Humans have used mirrors since as early as 600 BCE, employing highly polished obsidian as a basic reflective surface. Over time, people began to use small pieces of gold, silver, and aluminum in a similar manner, both for their reflective properties and for decoration. By the 1^st century CE, people had started using glass to make mirrors, but it was only during the European Renaissance that Venetian manufacturers began making mirrors by applying metallic backings to glass sheets, remaining the most common general method of mirror manufacturing today. Since then, mirrors have continued to play both a decorative and functional role in architecture, serving a clean, modern aesthetic despite its ancient origins. Below, we investigate how mirrors are made, provide a brief history of mirrors in architecture, and offer several tips for architects looking to use mirrors in their designs.

Until recently, the architecture world largely viewed plastic polymers as inferior building materials, handy for wipe-clean kitchen surfaces, but not practical in full-scale building applications. But with technological innovations driving material capabilities forward, polymers are now being taken seriously as a legitimate part of the architect’s pallet. One of the most widely-used of these materials is a fluorine-based plastic known as ETFE (Ethylene tetrafluoroethylene). Brought into the public consciousness thanks to its use on the facade of PTW Architects' Water Cube for the 2008 Beijing Olympics, architects are now realizing the film’s capabilities to express a new aesthetic and replace costlier transparent and translucent materials. Its most recent and spectacular public appearance was on the 120-foot telescopic shell of The Shed, designed by Diller Scofidio + Renfro and Rockwell Group in New York City.

Is there an aspect, a recurring mark, that reveals a difference in the way that male and female architecture photographers see the world? This is, perhaps, one of those rhetorical questions often used as an argument to shed light on works produced by women and for which there is no precise answer.

Without claiming to offer an answer to this question—and in order to follow up on our first article that showcased a selection of women in architecture photography—we present here a new compilation of professionals who deserve attention for the quality of their photographic work. See our list below:

Stone is elemental to our built world. It is one of the oldest (if not the oldest) materials used in man-made habitats. The sense of timelessness in stone is attributed to its long and varied history alongside architecture. From ancient monoliths to cities to houses, the diversity of stone means that it can be used to convey a variety of expressions. Carved, polished, sedimented, stacked, preserved - the list can go on and on. The feeling stone conveys in contemporary projects usually brings with it a sense of place – a raw materiality when paired with timber or other natural materials. With that in mind, check out these 6 details of projects that stand out for their use of stone:
