In 2000 more detailed research was undertaken on the areas looked at in previous years. Excavations revealed an ancient ditch, with rounded profile at the base; three early medieval burials without grave goods on an east-west alignment, delimited by bricks and partially cut by a sluice; a dry stone wall with external facing in stone blocks and loose fill on a north-south alignment; a roman wall on a lower level than the latter, constituted by limestone blocks on top of which were four course of sesquepedales bonded with mortar and with a layer of mortar on top.
