Alexander I Palace, Cultural heritage building in Taganrog, Russia.

Alexander I Palace is a one-story stone mansion at Grecheskaya Street 40 in Taganrog, built in the Russian classicism style. Its flat facade has 13 windows, rusticated corners, dentils along the cornice, and keystones above all windows; some windows carry triangular pediments while others have plain rectangular niches. The building has no colonnade.

The mansion was built in 1806 for the official Sivere and rebuilt in 1816 by architect F. Moll, then sold to the city as the governor's residence. Emperor Alexander I stayed here in 1818 and died here of fever on 19 November 1825. His widow bought the house and founded Russia's first memorial museum to the emperor, closed in 1928.

The building takes its name from the tsar who spent his final days within its walls, and it remains a reference point in the city's memory. Visitors walking past can still read in its plain facade the restrained style that marked official Russia in the early 1800s.

The building stands at 40 Grecheskaya Street, and its 13-window facade can be seen from the pavement. It now houses the children's sanatorium "Beryozka", so the interior is not open to visitors; the exterior is viewable at any time.

Tsar Alexander I spent his final days here in 1825, and this event is what gave the building its current name. This moment also led to the site becoming Russia's first memorial museum dedicated to a tsar, a distinction it held for many years.
