Puente y basílica de la Trinidad de Arre Monument · Ezcabarte, Comarca de Pamplona, Navarra In the concejo of Arre, on the right bank of the Ulzama river and on the boundary with Villava, stands a rural Romanesque basilica from the first half of the 13th century dedicated to the Holy Trinity, which still enjoys great popular devotion today. Beside it, a bridge of Roman origin with six arches — called the 'puente de Atarrabia' in the mid-13th century — allowed the Roman road, and later the Camino de Santiago coming from Roncesvalles, to cross the Ulzama. The attached pilgrims' hospital had twelve beds in 1584, attended by two hospitallers; it still provides hostel services today, run by a religious community.
