Palais Moy, City palace in Münchner Altstadt, Germany.

Palais Moy is a neoclassical city palace in Munich's Altstadt district, rising at the corner of Brienner Straße and Theatinerstraße. The three-story building displays a facade with fifteen window bays arranged in a balanced pattern that exemplifies early 1800s design principles.

Leo von Klenze designed the building, erected in 1824/25 on the site of police prefect Marcus von Stetten's house beside the Theatinerkirche. Jeweller Franz Xaver Trautmann was its first owner; in 1829 it was split into two numbered halves. The northern section passed to Count Aloys von Arco-Stepperg in 1830. His daughter Sophie married Ernst Graf von Moy de Sons in 1890, and the palace has belonged to that family since her death in 1952.

The name comes from Count Ernst von Moy de Sons, a royal Bavarian privy councillor of French noble descent who married Sophie von Arco-Stepperg in 1890; the childless couple's inheritance passed to the Moy de Sons counts in 1952, and they still own the building. Today shops and offices occupy the ground floor, whose large arched windows replaced the original small rectangular ones during the rebuild.

The palace sits in the heart of Munich's old town near the Theatine Church, making it easy to reach while walking through the historic district. Visitors can view its exterior from the street and easily incorporate it into an exploration of the surrounding architectural landmarks.

The palace's two halves, split into separate houses in 1829, were reunited during the 1950-1952 rebuild by architect Georg Hellmuth Winkler. A seam in the roof still marks where the division ran. The lavish Arco/Moy interiors, destroyed on 17 December 1944, had been photographed in 1932.
