Urban Oyster is leading tours of Most Holy Trinity on Montrose Avenue on December 17 and January 7. The church in its current incarnation dates to 1885 (William Schickel, architect), but the congregation itself goes back to 1841, when it was founded by German immigrants. It was the second Catholic parish in Williamsburg, and Brooklyn first National parish.

Urban Oyster does some great tours – this one is also for a good cause, to raise money for “Trinity Human Service Center, a nondenominational food pantry and charity that operates in the church basement”.
