Circular bronze base only. Globe sundial removed for repair at time of inspection. Information at site: 'The sundial is man's oldest astronomical instrument. The axis of this sundial lies parallel to the axis of the Earth and thus reproduces in miniature the way the Earth is bathed in sunlight. In this version the time is indicated by the fin which casts the least shadow. Due to a combination of the tilt of the Earth's axis and the varying speed of Earth's progress on its elliptical path around the sun, the indicated time will often differ by several minutes either way from mean time, the maximum being 16 minutes. The greatest differences occurring in February and October. One hour must be added to the indicated time during British Summer Time.'
The work was commissioned by Swansea City Council with sponsorship from Robert M. Douglas Holdings PLC, Lovell Urban Renewal Ltd., Milner Delvaux Ltd., and the Welsh Development Agency. It was unveiled by the Mayor of Swansea in July 1987. (Information at site)
