The St. Joris Church in Westzaan is a cruciform church, built between 1740 and 1741 with an ornate façade in Regency style, possibly based on a design by the Amsterdam carpenter Jan van der Streng. The foundation stone was laid on 19 May 1740, and the church was consecrated on 14 July 1741. The new building, shaped like a Greek cross, was constructed against the late-Gothic tower to the left of the previous church, which collapsed in 1843. That earlier church was dedicated to Saint George. Inside the church is an 18th-century pulpit, featuring a carving of a pelican feeding its young beneath the pulpit bowl.

The organ was built in 1866 by Flaes & Brünjes. This two-manual instrument was most recently restored and re-inaugurated in January 2002. Previous repair and restoration work was carried out by Bik in 1923, and more extensively by Flentrop in 1945. After dismantling the instrument during the church restoration in 1966, it was relocated in 1971, with further restoration of the pipework and revoicing completed by Flentrop in 1975.

The most recent restoration was carried out by Elbertse Orgelmakers. The casework, action, windchests, and keyboards were restored. The Prestant 4′ of the Bovenwerk (Upper Manual) was replaced with the original Prestant 8′, and the Terts stop was removed. The Salicional 8′ and Octave 4′ were replaced with a Salicet 4′ and Flute 2′, and a new Roerquint 3′ was added.

Since 1968, the church has been listed as a national monument in the Dutch Register of Monuments.
