Built on the land occupied earlier by the Corpus Christi hospital, one of the city's medieval hospitals. In 1558 the city exchanged plots with Archishop Esteban Almeyda and the hospital was relocated to the Parish of Santiago. The building may have started in the 16th Century, soon after the establishment of the Orihuela Bishopric. It underwent profound changes in the 18th Century under the reigns of Bishops José Flores Ososrio and Pedro Albornoa Tapia. In the mid-20th century, it lost its original functions, was restored at the beginning of the 21st Century and is currently home to the Diocese Museum of Sacred Art. At the back, facing the river, there is a gallery with semi-circular arches. Inside, another striking feature is the cloister with heraldic decoration, the main staircase of Alicante marble and the dome built on an octagonal base, with exterior cobalt blue glazed tiles.

Palmeral de Orihuela constitutes an interesting agricultural system of intensive irrigation of Islamic origin with date-trees situated on the borders of the banks, paths and irrigation canals. You can either reach this area by means of path tracking through el Collado del Oriolet, or go jogging or cross-country through the orchards of palm trees.

These magnificent limestone caves feature delicate shawls, grand columns, underground pools and amazing chambers.

The caves are set inside the deep gorges and rugged bluffs of the Yarrangobilly River Valley at the north of Kosciuszko National Park. Bring bathers to enjoy the natural thermal pool which is a constant 27°C.
