The Kaufmannskirche St. Gregor (Merchant's Church St Gregory) is a 14th-century Gothic parish church at Anger Square. It is one of the largest and most important original parish churches in Erfurt. The parents of Johann Sebastian Bach, Johann Ambrosius Bach and Maria Elisabeth Lämmerhirt married here in 1668.
The former Romanesque building (11th century) on the site was burnt down in 1291. The consecration of the Gothic basilica with twin choir towers took place in 1368. The altar (1625), pulpit (1598), baptismal font (1608), epitaphs (1584/85/90) are works of the Thuringian Late Renaissance and forms of Luther iconography of Erfurt sculptors and stone masons Hans Friedemann, the Elder and Younger. Martin Luther preached here on 22th October 1522.
References:The church of the former Franciscan monastery was built probably between 1515 and 1520. It is located in the UNESCO World Heritage Site of Old Rauma. The church stands by the small stream of Raumanjoki (Rauma river).
The exact age of the Church of the Holy Cross is unknown, but it was built to serve as the monastery church of the Rauma Franciscan Friary. The monastery had been established in the early 15th century and a wooden church was built on this location around the year 1420.
The Church of the Holy Cross served the monastery until 1538, when it was abandoned for a hundred years as the Franciscan friary was disbanded in the Swedish Reformation. The church was re-established as a Lutheran church in 1640, when the nearby Church of the Holy Trinity was destroyed by fire.
The choir of the two-aisle grey granite church features medieval murals and frescoes. The white steeple of the church was built in 1816 and has served as a landmark for seafarers.
