Tour maps of the Residenz, which has more than 120 rooms, lead through countless corridors and galleries, built in different eras for different Wittelsbach rulers, and it can be somewhat difficult to keep them all straight. Some rooms are worth lingering in, however. When it was completed by 1571, the long Antiquarium was the first addition to the original Neuveste. Although it was first intended as a gallery to house Albrecht V's sculpture collection, the 66m-long (216-ft.) hall was soon converted into a banquet room and it was definitely designed to impress. Sixteen ceiling paintings by Peter Candid (c. 1548-1628) portray fame and virtue, while depictions of 102 Bavarian towns by Hans Donau the Elder (c. 1521-1596) blanket the rest of the high vaulted ceiling. Admire the marble table in front of the chimney as well as the two credenzas by Friedrich Sustris containing rare majolica porcelain. The Grotto Courtyard, the royalty's secret little piece of Italy, links the Antiquarium with the Ancestral Gallery, an over-the-top celebration of gilded stucco and portraits that was intended to boast the Wittelsbach family’s claim to the throne (note the towering family tree midway down the gallery). The neighboring Porcelain Cabinet is an early Rococo gem, showcasing fine ceramic pieces in a mirrored room with gilded stucco by Johann Baptist Zimmermann (see the Wieskirche). Maximilian I's own private Ornate Chapel, with its dazzling blue-and-gold ceiling, was painstakingly reconstructed to its original design. The magnificent Imperial Hall and Staircase boast a riot of Baroque decoration, clearly intended to wow guests as they arrived to the court. François de Cuvilliés's Green Gallery, elegantly wallpapered in green silk damask, also arouses the imagination, given the lavish soirees that once occurred here.
