Girona Cathedral

The Cathedral of Saint Mary of Girona is not just the city's most iconic monument — it is a palimpsest of over a thousand years of history. Built on the site of an ancient mosque, which itself was raised over a Visigothic sanctuary, every corner holds layers of overlapping civilisations.

Its most astonishing fact: it boasts the widest Gothic nave in the world (22.98 metres), an architectural feat that challenged medieval engineers and continues to amaze every visitor who walks through its doors. From the 11th-century Creation Tapestry to the enigmatic Charlemagne keystone, the cathedral is a treasure chest of artistic wonders best explored at leisure — and with a knowledgeable guide.
