The Old Daphni Monastery was originally founded and built at the end of the 6th century, to the west of today's Athens. Surrounded by defence mechanisms, the monastery was extended with additional construction over time. The interior holds detailed mosaics and the complex is now a designated UNESCO World Heritage Site, which is worth the little detour by public transport.

This is one of the oldest churches in Italy – dating from the 5th century AD. Strange symbols and references to the Knights Templar can be seen, as well as the symbol of the pentagram near the church entrance. This is a must-see.

Built on the remains of the old Moorish mosque, the building started out as a Parish Church, ascending in importance, as Archiprestal (1281), Collegiate (1413) and finally becoming a Cathedral in 1510. Building started at the end of the 13th Century. It is of Levantine Gothic Style, with three naves and a gallery, a transept transformed by Pere Compte at the beginning of the 16th Century and side chapels between the buttresses. Of note inside is the ironwork, the Baroque organ, the work of Jacinto Perales and the choir stalls, made by Juan Bautista Borja and Tomás Llorens (1716-1718). The sacristy is home to the relics cabinet and cupboard, the work of José Ganga (1732-1734), holding diverse relics within a carved bust. On the outside, of note in the Tower, built between the late 13th Century and the mid-14th Century, the same as the three main gateways, The Puerta de Cadenas (14th Century), Puerta de Loreto (15th Century) and finally, the Portada de la Anunciación, completed by Juan Inglés in 1558.
