The Palacio Real de Madrid — the official residence of the Spanish royal family in the city — is Europe's largest royal palace, boasting a whopping surface area of 135,000 square meters and a staggering 3,418 rooms. This architectural marvel is not only visually stunning, but also features spectacular outdoor gardens and exquisite frescoes, furnishings, and paintings within its walls. Originally constructed in 1764 as a replacement for the Alcázar castle, which had been destroyed by fire three decades earlier, this magnificent edifice is a must-see attraction for visitors to Madrid. Nearly the entire palace is open to the public, including the Armoury and Pharmacy.

The preserve is a county-run park offering public access to a four-mile loop that allows hikers, bikers, and horseback riders. A collection of rare animals also make their homes in the area: Stephens' kangaroo rat, fairy shrimp, purple stipa, blue-eyed grass, and wooley blue curls are just a few. Bird watchers will enjoy the grand hawks that live in the grasslands as well.

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.
