Alongside the historic building of the Mariinsky Theatre II, built in 1860, and the Concert Hall which opened in 2006, the Mariinsky II will form part of this theatre and concert complex. The opening of the new theatre, equipped with the very latest and best technology, heralds the start of the new era in the history of the Mariinsky Theatre II. The exterior of the building is made of beige Jura limestone, interspersed with syncopated floor-to-ceiling windows of various sizes, and a metal roof. It was our privilege to have contributed to the success of such a high profile project and a greater pleasure to have collaborated with Diamond Schmitt Architects.
