The ensemble we know as Herrenhausen got its start in the 17th century as a country estate for the Electors of Hanover. Its notoriety grew with the addition of the Baroque Grosser Garten designed by Martin Charbonnier between 1696 and 1714, bringing to bear all the influence that his teacher André Le Nôtre exerted decades earlier at Versailles. At the same time, a residence was built to terminate the central axis of the expanding gardens. It was more than a century later, in 1819, after the territory had been elevated to a kingdom, that architect Georg Ludwig Friedrich Laves recast the structure with its restrained Neoclassical façade.

That legacy came to ruin during World War II, when a 1943 bombing raid leveled the castle, leaving only a crumbling horseshoe staircase. In the 1960s, restoration began on the garden, but the residence wasn’t rebuilt until last year, according to the Laves design, by Hamburg-based Jastrzembski Kotulla Architekten. Funded by the city of Hanover and the Volkswagen Foundation, the structure is now a conference center and museum, with contemporary spaces secreted behind the pediments and pilasters of the façade. With the reintroduction of this architectural centerpiece, the balance of the filigreed greenspace has been restored.

Schloss Herrenhausen is surrounded by many types of gardens, including this arrangement of fig trees and flower beds, which was restored to its original design by landscape architecture firm Hager Partner in time for the Expo 2000 world’s fair.

An entirely new below-grade level accommodates a large auditorium and additional seminar rooms. More contemporary than the interiors of the schloss proper, this level is illuminated and ventilated by two atriums cut into the main palace courtyard. Sliding doors connect these open-air spaces to the interiors.

Much of the schloss has been recast as a conference center, and the interiors combine classical proportions with modern finishes. The old foyer can be subdivided for smaller meetings and seminars; the space is paved in Jura limestone and opens out to the gardens. Conference attendees enter through a different entrance than that of the museum, which occupies the main level in the building’s east and west wings.
