You'll find a St. Mary's Church in Gdansk, Poland and a St. Mary's Church in Rostock, Germany.
These 2 churches are hard for me to tell apart. They have the same name. They are both large brick gothic buildings built in the 14th century. They both house an astronomical clock

St. Mary's Church in Gdansk claims to be the largest brick church in the world.

Yours in wondering just how many bricklayers and clockmakers there were in the 14th century,
