Pamplona is the main town in the Spanish Pyrenees region. The former capital of the kingdom of Navarre, it has retained the appearance of an old fortified town in the narrow streets around the cathedral. Sections of its old walls remain to the north and east, while modern districts have developed to the south: long avenues lined with sleek buildings (Paseo de Sarasate), arcaded squares (Plaza del Castillo). The walled town is surrounded by a ring of parks. Pamplona is a festive city known for its bullfights and corridas during Sanfermines. In the evening, stop off in one of the lively bars in Calle Estafeta, Calle San Nicolás or Calle Navarrería to sample a few pinchos.
