In the 18th century Decoy Pond House stood at the point where a plank was used to cross the Bourne Steam on the track from Poole to Christchurch.

In 1848 composer Hubert Parry was born next door to The Square and is marked with a blue plaque.

In 1925, a tram shelter was built at the center of the Square, with a clock on the top, which was given by Captain HB Norton, a magistrate and former Councillor.

The roundabout was removed in October 1992, and since 2000 the square has been almost totally pedestrianised.

The old clocktower is now the site of the Obscura Café, so called because it once incorporated a functioning camera obscura, and the clock was installed at the top of the cafe.
