Weert's major church is the St. Martinus, a Gothic hall-church from the 15th and 16th century. The lower half of the  tower dates from 1528-1529 and was built in a style that is closely related to Campine Gothicism. In 1887-1889 a new segment was added, designed by J. Kayser. In 1958-1960 the lantern was added, which was design by Th.G. Verlaan.

The Paterskerk is a two-aisled Gothic church from the early-16th century. Originally it belonged to a Franciscan monastery.

The St. Rumolduskapel is a small chapel which was built in ca. 1775.

The reformed church was built in 1910-1912 after a design by G.W. van Heukelom. 

P.Cuypers Jr. designed this Kloosterkapel (monastery chapel) from 1911.

The St. Joseph in the Keent neighbourhood was designed by A.J.N. Boosten and built in 1939-1940. Like many of Boosten's churches it features both Expressionistic and Traditionalistic elements.

The Onbevlekt Hart van Maria or Fatimakerk dates from 1953-1955 and was designed by P.H. Weegers, who seem to have been inspired by the work of A.J.N. Boosten.

The H. Hart van Jezus of Altweerterheide, a little outside the actual Weert, was built in 1935-1936 after a design by J.Th.J. Cuypers and his son P. Cuypers Jr..
