The Citadel of Pamplona

It is the best example of military architecture from the Spanish Renaissance.
It was built during Felipe II´ s reign in order to face the French army, replacing Fernando el Católico´ s castle. It has a combined surface area of 280 000 square meters. Its structure has the form of a regular pentagon with five bastions in its corners, from which only three of them have arrived to our days.
The construction of the First Enlargement of the town supposed the demolition of two of them.

It keeps the stone siege with a batter that surrounds it. It has two doors: the main one is oriented to the old part of the town, and the second one is the emergency door. Inside, other fortifications and smaller buildings are used nowadays as public leisure and culture places. In the XVIII Century, it became a prison for distinguished men, such as the count Floridablanca.
