Forts were set up at Bath and Ilchester. The lead and silver mines at Charterhouse in the Mendip Hills were run by the military. The Romans established a defensive boundary along the new military road known the Fosse Way (from the Latin "fossa" meaning "ditch"). The Fosse Way ran through Bath, Shepton Mallet, Ilchester and south-west towards Axminster. The road from Dorchester ran through Yeovil to meet the Fosse Way at Ilchester. Small towns and trading ports were set up, such as Camerton and Combwich. The larger towns decayed in the latter part of the period, though the smaller ones appear to have decayed less. In the latter part of the period, Ilchester seems to have been a "civitas" capital and Bath may also have been one. Particularly to the east of the River Parrett, villas were constructed. However, only a few Roman sites have been found to the west of the river. The villas have produced important mosaics and artifacts. Cemeteries have been found outside the Roman towns of Somerset and by Roman temples such as that at Lamyatt. Romano-British farming settlements, such as those at Catsgore and Sigwells, have been found in Somerset. There was salt production on the Somerset Levels near Highbridge and quarrying took place near Bath, where the Roman Baths gave their name to Bath.
