terrace atop one section of the building. It was built of steel, concrete, and stone, but also with pine wood and other materials recycled from demolished factories. Jule Iovine, architecture critic of the Wall Street Journal, called it "a welcoming, creative machine" thanks to its "open, changeable spaces," and Michael Kimmelman, critic of the New York Times, called it "an outdoor perch to see and be seen... There's a generosity to the architecture, a sense of art connecting with the city and vice versa". The Harvard Art Museums, Cambridge, Massachusetts (2008–2014) Beginning in 2008, Piano rebuilt an existing structure to house the Harvard Art Museums, a consolidation of collections of the three art museums associated with Harvard University. The new museum preserved the picturesque brick Ivy-League facade of the 1925 Fogg Museum (1925), but added a new space in the courtyard, covered by a pyramidal glass roof, which increased the gallery space by 40 percent. The renovation adds six levels of galleries, classrooms, lecture halls, and new study areas providing access to parts of the 250,000-piece collection of the museums. The new building was opened in November 2014. Valletta City Gate and Parliament House, Malta (2011–2015) The 'City Gate' project in Valletta, Malta was the complete reorganization of the principal entrance to the Maltese capital of Valletta. It included a massive City Gate through the 16th-century city walls, an open-air theatre ‘machine’ within the ruins of the former Royal Opera House, and the construction of a new Parliament building. The gate project was controversial, though the old gate it replaced was only built in the 1960s, in the Italian rationalist style. The "theater machine" is particularly unusual; the original idea was that in summertime a steel portable theater with stage and wings and a thousand seats can be installed inside the ruins of the 19th century opera house, which had been destroyed in World War II. It has its own stage equipment and technology for reproducing the acoustics of a traditional opera house. When performances are not taking place, the "machine" was meant to turn back into a public square and gathering place. The Parliament House (2011–2015) is a mixture of modern technique and technology with the massive stone look of the city's old walls.
