Banu Church, Romanian Orthodox church in Iași, Romania.

Banu Church is a Romanian Orthodox church building in Iași featuring Baroque architecture with a trefoil floor plan, large windows framed by stucco ornaments, and a bell tower positioned above the entrance vestibule.

The first church on the site was a wooden one built in 1704 by the great ban Savin Zmucila, blessed by Metropolitan Misail and dedicated to the Dormition. By 1799 it was too small and in disrepair, so Metropolitan Iacob Stamati and the parish funded a new stone church, completed in 1800 to a design by the Transylvanian architect Herr Leopold. It is the oldest church in Iași whose inscription names its architect.

The carved linden iconostasis was made and painted by Eustație Altini in 1802; he began the interior painting in 1803 but left it unfinished after Metropolitan Iacob Stamati died that March. A Madonna and Child mural, possibly by Altini, was found during 1968 plaster repairs. The church was also called the Beggars' Church after the guild that worshiped here.

The church is located on Strada Banu 9 and is easily accessible by public transportation in the city center. Visitors should plan their trip with flexible timing, as occasional religious services or events may affect access during regular hours.

The wooden church that stood here from 1704 was the first in Moldavia where services were held exclusively in Romanian, reportedly partly as a protest against the Greek and Slavonic liturgies of other Iași churches. Its founder, the great ban Savin Zmucilă, also ran a shelter for the poor and sick beside it, which operated until 1948.
