Prince Albert spent much of his childhood in Schloss Ehrenburg, the ducal palace. Built in the mid-16th century, it has been greatly altered over the years, principally following a fire in the early 19th century. Duke Ernst I invited Karl Friedrich Schinkel from Berlin to redo the palace in the then-popular neo-Gothic style. Some of the original Renaissance features were kept. The rooms of the castle are quite special, especially those upstairs, where the ceilings are heavily decorated with stucco and the floors have wonderful patterns of various woods. The Hall of Giants is named for the larger-than-life caryatids that support the ceiling; the favorite sight downstairs is Queen Victoria's flush toilet, which was the first one installed in Germany. Here, too, the ceiling is worth noting for its playful, gentle stuccowork. The baroque chapel attached to Ehrenburg is often used for weddings.
