The first Anglican church at St Leonards was opened in 1847.

St. Peter’s Church, Patterson’s Plains.— This neat little edifice, so much required by the settlers at Patterson’s Plains, was opened for divine worship on Sunday last [18 April], and the sum of seven pounds collected in aid of the Building Fund. The church is finished, with the exception of the interior ornaments and fittings, which are intended to lie perfected as soon as possible. We are desired to notice that the Rev. Mr. Williams will officiate there next Sunday.
