One of the destinations on this route is the
Santuario de los Santos Antonios in Urkiola, a monumental work that has received many visitors. It is spread over three naves of differing heights, the central nave being higher than the two side naves. The work dates from the 19th century, with a historicism influenced interior and some neo-Romanesque details. This Sanctuary, located in a stunning natural landscape, was preceded by another religious building of which there remains a tower in two sections with a bell-tower at the top and the top part has a well-accomplished bulbous dome.
