Heritage Open Days in Southampton

In September, thousands of heritage sites across England will open their doors once again to the public, including some of Southampton’s most iconic sites, for Heritage Open Days. Since its establishment in 1994, this volunteer led event continues to grow in size making it the largest community event of British history and culture. All sites participating in the event are free to visit.
