Pilgrimage attested historically; not continuing

This page groups sacred sites by how active they still are as pilgrimage destinations. Wikipedia notes that Santiago de Compostela "remains a significant pilgrimage site, with around 200,000 pilgrims, both secular and Christian, completing the numerous pilgrimage routes to the cathedral in 2012 alone." Browsing this way lets a visitor tell a heavily visited pilgrimage site apart from one now visited only rarely.
