Stirling Square is a picturesque park that is one point of interest on a self-guided walk through historic Guildford.

Stirling Square originally called Church Square, was set aside and surveyed in 1829. It was originally twice its current size but in the 1940s and 1860s, sections were sold off and trees were planted in 1874 and 1897.

In the centre of Stirling Square is St Mathew's Church. This is the third St Mathews Church in the area. The first, built of mud bricks in 1836 was replaced by a wooden building which was blown down by a hurricane in 1860. The current building was constructed in 1873 and is notable for the way the bricks have been laid alternately lengthwise and pointing inwards to reinforce the structure.

The Stirling Square Markets are held on the third Sunday of each month from February to November. There is also a Christmas market in December and a monthly twilight market from October to April.
