Al-Rajhi Grand Mosque stands as one of the largest places of worship in Riyadh. Its vast prayer halls can accommodate over 20,500 worshippers, and the complex functions as a comprehensive Islamic centre with libraries and educational facilities. While entry is reserved for Muslims, the impressive exterior architecture, particularly striking when illuminated after dark, makes it a notable city landmark. The mosque's scale and community role underscore its significant position within the capital's religious and cultural landscape.

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.

The Arkas Art Center is a small yet quite impressive art gallery with a commendable art curatorship. Housed in a historic and visually striking building, the centre takes pride in being the first in İzmir to showcase the works of numerous renowned international painters, including Picasso.
