Wealthy German businessman and brewer Christian Heurich built this turreted, four-story brownstone and brick Victorian castle in 1894, and lived here with his family until he died in 1945. Old Heurich was a character, as a tour of the 31-room mansion/museum reveals. Allegorical paintings cover the ceilings, silvered plaster medallions festoon the stucco walls, and a bierstube (tavern room) in the basement sports the brewer’s favorite drinking mottos—written in German, but here’s one translation: “There is room in the smallest chamber for the biggest hangover.” The Castle Garden is a good place to pause for a picnic or page through your guidebook. Enter the garden through the east gate on Sunderland Place NW.
