The archaeological excavation of an important Roman site begins in Swindon on Wednesday.
The work is taking place at Groundwell Ridge in the north of the town.
Previous digs have unearthed evidence of well-preserved Roman buildings, pottery and coins dating from the second to fourth Century AD.
This year's activities will focus on one of the buildings damaged when the site was discovered by construction workers in 1996.
The seven-week dig is funded by English Heritage.
Archaeologists say the site is of great historic importance.
