on either side of the fountain are two large sculptures collectively known as "guardians". the sculptures – made from the same darley dale stone as the council house – are high, wide and long. the sculptures are not identical and take features from a variety of animals. they have been derided in the past for having faces like characters in the children's television series "thomas and friends". on either side of these sculptures are two obelisk-shaped sculptures collectively known as "object (variations)". the sandstone sculptures are tall and . the two obelisks were initially refused by the city council, as they were deemed unnecessary; but mistry – who declined to comment on their meaning – urged the council to reconsider, and they were later approved. they now act as lampstands in the square.
