The Hospital of St Thomas of Acre was the medieval London headquarters of the Knights of Saint Thomas, founded as a church in 1227[1] in the parish of St Mary Colechurch, birthplace of the order's patron saint, Saint Thomas Becket.

From the 14th century, it was the main headquarters of the military order.

[2] In 1512, the Worshipful Company of Mercers bought from the order a site by the church on which to build its hall.

The properties were forfeited to the crown and subsequently acquired by the Mercers in exchange for various payments, rents, and undertakings.
