The Zion Evangelical Lutheran Church is located on Route 24 on the banks of the South Branch of the Raritan River.

In 1832 the Old Union Church was abandoned for the new more impressive edifice on Route 24. This stone church building with stucco wing probably dates to its early construction date. but also exhibits numerous Gothic characteristics as reflected in the Gothic arch windows and doorways and the octagonal spire. Even with a projected center vestibule tower. the Evangelical Lutheran Church. maintains a basic rectangular form.

The front facade of the edifice has a tower which extends to a point just above the roof peak of the main building. The vestibule has a double door capped by a Gothic arched transom. In the transom is a stained glass circular window. Above the entrance are two paired Gothic arched windows which are highlighted brownstone. The tower has a wooden hiproofed capping and is topped by a full one story towered belfry and a reaching octagonal spire. Flanking the tower are Gothic tracery windows with stained glass. The long facade of the church has five bays; all Gothic arch tracery with stained glass windows.

A modern one story flat roofed stone and concrete multi-purpose facility has been added to the south.
