Andronikov Monastery of the Saviour (Russian: Андро́ников монасты́рь, Спа́со-Андро́ников монасты́рь, or Андро́ников Нерукотво́рного Спа́са монасты́рь) is a former monastery on the left bank of the Yauza River in Moscow, consecrated to the Holy Image of Saviour Not Made by Hands and containing the oldest extant (i.e. outside the Kremlin) building in Moscow. It is home to Andrei Rublev Museum of Old Russian Art, named after the most famous monk of this abbey.
Since the 1930s, when the Communists destroyed the 14th-century Saviour Cathedral in the Wood, the monastery's cathedral has attracted a renewed interest as the oldest preserved in Moscow. Consequently, its present outlook is the result of a controversial Soviet restoration (1959–1960), which sought to remove all additions from later periods. Nothing but traces of the frescoes by Andrei Rublev and Daniil Chyorny remain visible on its walls.
The second oldest monument (1504–1506) in the abbey is a spacious refectory, the third largest such structure after those in the Palace of Facets and Joseph-Volotsky Monastery. The adjacent baroque church was commissioned by Eudoxia Lopukhina in 1694 to commemorate the birth of her son, Tsarevich Alexis, and contains a burial vault of the Lopukhin family.
Massive 17th-century walls and towers are reminiscent of the period when the monastery defended the eastern approaches against the Moscow Kremlin. In 1795, they started a Neoclassical belltower, one of the tallest in Moscow. This astonishing belfry was destroyed in 1929–1932, and its bricks were subsequently reused in construction of nearby buildings.
