Buildings and structures in Sheffield have been constructed over a time-span ranging from the 13th century to the present day.
At the time of the Norman Conquest Sheffield was a small hamlet dominated by a wooden long house occupied by Waltheof, 1st Earl of Northampton, which later became the site of the two castles.
The Domesday Book, which William the Conqueror ordered to be written so that the value of the townships and manors of England could be assessed, mentions :- Beauchief Abbey was built four miles south-west of what was then a well-established town.
In November 2005 the University of Sheffield's archaeological consultant, ARCUS, unearthed a Medieval well over three metres deep in the sandstone bedrock beneath Carmel House on Fargate.
The uncovered medieval pots included jugs made in the Hallgate area of neighbouring Doncaster and other items from the Humber Estuary.
Due to the conditions in the well, animal bones and plant remains (possibly including microscopic pollen grains) have been preserved and will be analysed the University's Department of Archaeology laboratories.
Many residential buildings were constructed at the turn of the 20th century, which led to the annexing of large parts of the current city.
The years following the Second World War saw one of the most intense periods of building in the city's history, referred to as the slum clearances.
The £315 million West Bar scheme includes new university buildings, a boutique hotel, and residential and commercial developments.
