The Roman wall in Horncastle enclosed an area of around five acres and was built in the early 3rd century. The wall was 3.6 metres wide with facing stone leafs with a lime rubble core.  The stone was a green sandstone which was quarried near Tetford. The picture on the right is a part of the wall which can still be found behind the local community centre.  The picture below is a part of the wall which is visible in the local

library. There is several other places around town where the wall is still in evidence also.  

The only section which still as some of the original facing stone is to be found behind the Manor House on Manor House road, there excavated is one of the corners complete with dressed stone.  To view it though permission must be sought as it is on private land, I have recently been and photographed this section and the picture is the bottom left one.  Below is a section in dog kennel yard.  I will keep adding pictures as and when I obtain them of the different sections that are visible.

The area within the fort was not lived in during Roman times, but was probably used as a safe haven during times of crisis.  The main civilian settlement was south of the river Waring covering quite a large area.  There have been many local finds of pottery and coins as well as other artefacts.  A few of these can be seen at the local tourist information centre which is based in the 

Trinity centre on Spilsby Road in the town.  On the outskirts around Horncastle there were several Roman villas also, the   three  I know of were at Dalderby, West Ashby, and Wood Enderby.
