Holy Trinity Church, Trinity Green, Haslar Road, Gosport, PO12 1HL

..after 12 tonnes of rubbish were removed together with ivy and brambles, No.1 Bastion, emerged!
As part of the Gosport Lines which protected the town, it was the first section to undergo restoration under Gosport’s Heritage Action Zone.

This Bastion was constructed, by convict labour, in about 1802. The Gosport Lines are an exceptionally rare system of 17th to mid-19th Century earthwork defences that encompassed the town and several harbour-based military sites.

The Bastion is a Scheduled Ancient Monument and the moat is designated as a SINC Site of Importance for Nature Conservation.

Learn all about the history and future plans for Trinity Bastion, officially known as No.1 Bastion (and by many older locals as ‘Vicar’s Bank’ or ‘Tragedy Bank’) in this exhibition put on by the ‘Friends of Bastion No 1’ who will be around to chat to and answer any questions. This will be held inside the historic and beautiful Holy Trinity Church.

*And if the exhibition hasn’t totally quenched your thirst, you can pick up a self-led trail sheet and take yourself on a walk around the Bastion and Ramparts. More info on the event ‘What Lies Behind the Wall…? (Trail)’
