Cultural tourism is becoming an increasingly important part of the wider tourist industry. The Lake District's links with a wealth of artists and writers and its strong history of providing summer theatre performances in the old Blue Box of Century Theatre are strong attractions for visiting tourists. The tradition of theatre is carried on by venues such as Theatre by the Lake in Keswick with its summer season of six plays in repertoire, Christmas and Easter productions, and the many literature, film, mountaineering, jazz and creative arts festivals, such as the Kendal Mountain Festival and the Keswick Mountain Festival.
