There are a number of places of worship in Summer Hill.
St Patrick's Catholic Church was built in 1874, and is the oldest known building in the suburb.
There is also a small primary school associated with the church and located next to it.
The building was originally a private home known as Kelvin Grove, and owned by Mrs Jane Drynan.
Much of the exterior of the church is original but none of the internal walls were retained when the building was converted into a church.
Following Drynan's death, Kelvin Grove was owned or leased by a succession of different people, including the Haberfield real-estate developer Richard Stanton, Croydon brick-maker William Downton, and two sisters named Freeman (one of whom was a nurse).
In the 1920s and 1930s Kelvin Grove may have been used as a nursing home.
The first mass was celebrated in Kelvin Grove on St Patrick's day 1946, giving the church its name.

St Andrew's Anglican Church has three distinctive internal transept arches, and was designed by a Presbyterian, Alexander Leckie Elphinstone Junior.
The foundation stone was laid in 1883, and the top of the spire completed in 1906.
The fast construction period, unusual for that time, was indicative of the area's affluence.
Recent Asian influences in Summer Hill have brought about the introduction of non-Christian places of worship.
The Wong Tai Sin (or Kwan Yin Kur) temple is located on the corners of Kensington Road and Liverpool Road in a building that was a Masonic temple in the 1920s.
The same building was converted into the current temple; the lower floor houses the Taoist deity of Wong Tai Sin, and the upper floor houses the Buddhist Bodhisattva of Kwan Yin.
