The Ebro Bridge in Tudela is an impressive example of medieval architecture. Built of stone, it spans 360 meters and consists of 16 piers and 17 uneven arches. This bridge is fundamental to the history of Tudela, as it has been a strategic crossing over the Ebro River since its construction in the 12th and 13th centuries. Although tradition attributes its construction to King Sancho VII the Strong, some historians suggest it may be a reconstruction of an earlier Muslim bridge. Over the years, it has undergone numerous renovations to withstand floods and the ravages of time.

Castildetierra is a natural formation created by water and wind erosion; a stone placed on top protected the ground below, creating a sort of earth pyramid. The soil has different shades, and at sunrise and sunset it takes on extraordinary reddish hues.

As we passed through Tudela, we were lucky enough to unwittingly witness the first running of the bulls of the town's festival. We were able to watch the running of the bulls (8:00 AM) from the hotel, right in front of the last curve before entering the square. Afterwards, we started our route toward Zaragoza-Pinseque.

Entrance to Tudela via the bridge over the Ebro River. Beautiful view of the old part of the city and the river.
