The Ta' Liesse Church at Telgħet Ta' Liesse has an adjoining Chaplaincy located on its left. The Chaplaincy has simple façade architecture and is somewhat closer to the style prelevant during the late 1940s. The Chaplaincy was damaged during World War II and the façade and roofs were rebuilt. This Chaplaincy is also the Malta office for the Apostleship of the Sea which attends to seamen's spiritual needs.

The building consists of three floors. The ground floor has a plain door with a framed window and moulded sill. On the first floor, the façade has a wooden balcony supported on three corbels, which nearly occupies the entire width of the façade. The second floor has an open, iron-railed window within a receded alcove, and at roof level it has a simple cornice with a plain roof parapet.

Mepa scheduled the Chaplain's residence annexed to the Church of Our Lady of Liesse as a Grade 2 national monument as per Government Notice No. 276/08 in the Government Gazette dated March 28, 2008.
