Heritage Open Day: Discover one of the best preserved Roman Walls (ROMANS) in the whole of the United Kingdom, get up close to this ancient monument and discover facts about life as a Roman Soldier. From Caistor Roman Town to Burgh Castle and on to St Benet's Abbey, 3 iconic heritage sites in Norfolk will host a geocache challenge for everyone to enjoy. To celebrate HOD's 30th Anniversary, we invite everyone to travel the route, network together and make connections to their cultural past. You can participate in as much or as little as you like, just get out in the fresh air, learn something new and enjoy the beauty of these special places.
