It's one of Sheffield's most recognisable landmarks, the city's tallest public building and the tallest university building in the UK.
While the rest of the city has changed around it, the University of Sheffield's Arts Tower has stood imperiously above it all as a reassuring constant amid the constantly evolving skyline.
It's nearly 60 years since the 78-metre tall building on Bolsover Street was officially opened by the Queen Mother in 1966, at which point it was easily Sheffield's tallest building. This retro photo gallery takes a look back at its history, from its construction in the 60s right up until the early 2000s.
The pictures include the royal opening, stunning views from the rooftop which show the city's shifting landscape, and some of the events which have taken place in its shadow over the years, including at Crookes Valley Park and Weston Park.
From these photos, it's easy to see why the Arts Tower, with its equally famous paternoster lift, was once described by English Heritage as 'the most elegant university tower block in Britain of its period'.
