Weiler Building, Historical building in Makrygianni, Greece

The Weiler Building is a structure in Makrygianni, Athens, completed in 1836 and named after its architect, Bavarian engineer Wilhelm von Weiler. It stands opposite the New Acropolis Museum, with the Makrygianni archaeological site in its forecourt. Today it houses services of the Ephorate of Antiquities of the City of Athens, including the Acropolis Studies Centre.

The building was completed in 1836 to designs by Bavarian engineer Wilhelm von Weiler and served as a military hospital until 1918. A fire damaged it in 1849, and it was renovated in 1899. In 1920 it passed to the National Defence Fund, and in 1930 a Gendarmerie force was installed; from 1938 it housed the Makrygianni Gendarmerie Regiment.

Inside the building, a center dedicated to Acropolis history displays plaster casts and original terracotta fragments from different periods. These collections help visitors understand how the ancient site's buildings and decorations changed over time.

The building is located on Makriyianni Street and is easily accessible on foot from the Acropolis Museum area. Visitors should note that the site functions primarily as a research facility, so visiting may require advance arrangements or may be limited.

During the battles of 1944, the building's original coated surface was damaged and removed, exposing the natural stone beneath. These visible marks remain today and tell the story of the turbulent events Athens experienced during that period.
