[1] It was built in the late 1990s as part of the harbourside regeneration and We The Curious (then named @Bristol) development, and has become a popular public area and event space.
[4] We The Curious, a hands-on science museum, stands to the north in a grade II listed former railway goods shed, behind a reflecting pool that runs the length of the square.
The museum's planetarium – a 15-metre (50 ft) diameter sphere clad with mirrors designed to appear to float in the pool – is a prominent landmark in the northwest corner of the square.
[2] Along the east side of the square is a large water sculpture, Aquarena, designed by William Pye,[5][6] containing fountain walls and terraced cascades, which is often used as a paddling pool on warm days.
Regeneration proceeded slowly, and by the mid-1990s the only developments to have been completed were Canons House and Lloyds Amphitheatre, adjoining Millennium Square to the south, and the conversion of some of the quayside transit sheds to hospitality and cultural uses to the east.
