Best churches to visit worldwide

This is the widest group in the catalogue: parish churches, royal abbeys that are no longer abbeys, pilgrimage churches and a few buildings that are churches in the most unusual sense. It includes the rock-hewn churches of Lalibela in Ethiopia, carved down into the stone; the Salt Cathedral of Zipaquirá in Colombia, built inside a salt mine; Westminster Abbey, where English monarchs are crowned; the Gergeti Trinity Church beneath Mount Kazbek in Georgia; the medieval frescoes of the Boyana Church in Sofia; and the carvings of Rosslyn Chapel near Edinburgh.
