Santillana del Mar

Village

Santillana del Mar is known across Spain as the village of three lies: neither holy (santa), nor flat (llana), nor on the sea (mar).

Region: Costa de Cantabria Province: Cantabria Type: Village Population: 4,200 (2024)

What it actually is

An almost intact village of escutcheoned stone houses and cobbled streets, two kilometres inland. Its survival is deliberate: the collegiate church became a national monument in 1889.

The Colegiata, and when to come

The anchor is the Colegiata de Santa Juliana, a 12th-century Romanesque church and former Benedictine monastery; its cloister, added around 1200, holds the best Romanesque carving on this coast. The warning is timing: every coach itinerary stops here.

Before ten in the morning or after six; staying overnight is surest.
