Michaelertrakt, Imperial palace facade in Innere Stadt, Austria

The Michaelertrakt is the northern facade of the Hofburg in the Innere Stadt in Vienna, Austria. Its curved front follows the line of Michaelerplatz, with a large green copper dome above the central arched gateway, paired columns, statues in niches and four Hercules groups carved from 25-tonne blocks. Two fountains, "Austria's Power at Sea" and "Austria's Power on Land", stand before it, their figures of Laas marble and basins of red Uddevalla granite.

Joseph Emanuel Fischer von Erlach won the competition against Johann Lucas von Hildebrandt's 1725 scheme with his Project II of late 1725; his Project III of 1726 was built only in 1889–1893, slightly modified by Ferdinand Kirschner during the Ringstrasse development. The foundations had to reach 16 m deep because the demolished houses and the old Hofburg theatre stood on up to three cellar levels.

The Michaelertrakt marks the main entrance to the Hofburg and serves as one of the most used passageways in the city center. Stepping through the gate, visitors move in a few steps from the open square into the quieter inner courtyards of the former imperial residence.

The Michaelertrakt is easy to spot from Michaelerplatz, which is directly reached from Kohlmarkt. Those who want to see the sculptural groups on the facade up close should take some time and approach the building from different sides.

Excavations carried out beneath Michaelerplatz in the 1990s uncovered remains of Roman-era and medieval buildings directly under the square. These finds are visible today in a small open display area on the square itself.
