St. Catherine's Monastery, Tallinn

It is located in the heart of Tallinn's Old Town district full of warehouses and merchants' houses.

The site, between present-day Vene and Müürivahe streets, was chosen carefully so as to facilitate both the friar's ability to preach to a large audience, and to suit their business interests, as they are known to have traded in fish.

The monastery also had a brewery, producing four types of beer.

Throughout the Middle Ages, the monastery was renowned for its scholarship.

Parts have been incorporated into the Roman Catholic St. Peter and St. Paul's Cathedral, and other parts, including a finely carved portal, are visible via St. Catherine's Passage (Estonian: Katariina käik), connecting Vene and Müürivahe streets.
