St Peter's dates mainly from the 13th century, but parts are older than that. It was recently discovered that the pillars of this church stand on the site of an earlier building. Evidence has shown that there was once an important Saxon church in Oundle. Perhaps this is the site of more than 1,000 years of continous worship.
Construction of the tower started in the late 14th Century, and was completed in the 15th century. The spire is dated 1634, which is the date in which it was re-built. The porch was built in 1455 at the expense of Robert Wyatt, a merchant of the day. The room above the porch may have been used as a schoolroom at some point.
