Sheffield nestles on the eastern foothills of the Pennines and is sculpted by a dramatic hill-and-valley system formed where five rivers — the Don, Sheaf, Rivelin, Loxley and Porter — converge, producing steep-sided valleys and gritstone ridgelines with much of the urban area built directly onto hillsides…

Birmingham is a snowy city relative to other large UK conurbations, due to its inland location and comparatively high elevation. Between 1961 and 1990 Birmingham Airport averaged 13.0 days of snow lying annually, compared to 5.33 at London Heathrow. Snow showers often pass through the city via the Cheshire gap…

The west of the county lies on more resistant Cretaceous chalk. This chalk is responsible for a sweeping tract of largely downland landscapes that stretches from Dorset in the south west to Dover in the south east and north through East Anglia to the Yorkshire Wolds. The chalk is less easily eroded so forms…

Cambridgeshire has a maritime temperate climate which is broadly similar to the rest of the United Kingdom, though it is drier than the UK average due to its low altitude and easterly location, the prevailing southwesterly winds having already deposited moisture on higher ground further west. Average winter…

The name Bury is etymologically connected with borough, which has cognates in other Germanic languages such as the German burg meaning "fortress, castle"; Old Norse borg meaning "wall, castle"; and Gothic baurg meaning "city". They all derive from Proto-Germanic *burgs meaning "fortress". This in turn derives…
