Arab tower and site of Silla Monument · Silla, L'Horta Sud, Valencia Image of Silla, not of the place itself. Remains of an Islamic-era tower next to the Museum of History and Archaeology of Silla, evidence of the municipality's fortified Muslim settlement. The tower was built in the 7th century, and in the 12th century it was rebuilt reusing ashlars from Roman villas; after the Christian conquest it served as the nerve centre of the encomienda of Silla under military orders. The site on which it stands dates from the 1st-2nd centuries, with finds of coins, millstones and pottery fragments. Restored in 1984, it has housed the MARS (Museu d'Història i Arqueologia de Silla) since 2009. Photo: B25es (CC BY-SA 3.0) What to see and do in Silla
