The Markgräfliches Opernhaus is an architectural treasure. Designed by Joseph Saint-Pierre, this grand structure was built circa 1744. Since its opening, this venue has had the honor of being the premier location for the city's major events, including some royal weddings. Built of wood and canvas, this magnificent Baroque structure is remarkably well-preserved and is a rare treasure indeed. With its lavish décor, acoustical sound design and rich paintings, the opera house's designation as a UNESCO World Heritage Site should come as no surprise. The opera house is open to visitors and also provides tours.
