Yes. Not to be confused with historic Lewes, Delaware.
Lewes is old and unspoiled but due to its proximity to Brighton (large and very alternative) and the two Universities (Brighton and Sussex) it is full of liberal middle class lecturers and ex-hippies as well as the county set. There’s a strong sense of community and an interest in environmental causes. This can mean some eccentric, extreme and/or idealistic individuals and groups, which you have to accept as part of the charm, but also some quite practical (if radical) initiatives like the above.
