Nestinari is a traditional Bulgarian ritual that involves dancing on hot coals. This unique practice is often performed during the summer solstice and is associated with the celebration of the Saints Constantine and Helena. Participants, known as nestinari, enter a trance-like state, believed to connect them with spiritual forces. The dance is accompanied by live music, typically featuring traditional instruments like the gaida (a type of bagpipe) and drums. Nestinari believe that the fire has healing properties, and the ritual is a way to invoke blessings for health and prosperity. This cultural practice is recognized as part of Bulgaria's intangible cultural heritage.
