In Perugia there is a pretty active GBLT community which doesn’t only promote events but with help of volunteers also organize cultural initiatives. The point of reference is the association omphalos located in via della Pallotta, 42 open on Mondays, Wednesdays and Fridays from 3 to 7pm offering services like infopoint, library, free wifi and cafe.
