Coins from the seaside. An Emiral silver coin hoard from a harbour settlement on the Cerro da Vila (Vilamoura, Algarve, Portugal)

Cerro da Vila was founded as a Roman production and harbour settlement (“agglomeracion secundaire”) at the end of the Republican Age. It developed into a small seaside settlement (“aldeia do mar”), largely based on the exploitation of maritime resources, although it is unlikely that this exploitation exceeded-subsistence level. The abandonment of the settlement probably resulted from violent attack and destruction at the end of the 11th / beginning of the 12th century AD. A hoard of 239 silver coins and fragments were discovered at the bottom of an Islamic storage pit dug into the ground in an area of the former Roman site, where several remains of buildings and layers confirm settlement activity in the Visigothic and Islamic period. The latest coin is dated 270/883-4, but the hoard might have been buried some years later. It is likely that the hoard represents a small random sample of the coin circulation in Gharb al-Andalus. Most of the coins are fragmented. As it is typical for that period, a number are slotted and slashed coins; some of them are plugged with tiny pieces of silver. With the exception of two Carolingian deniers all the identifiable coins are from Cordoba, proving a tight control of the circulation of coins in al-Andalus. The hoard belongs to a horizon of similar hoards from southern and south-western al-Andalus which were buried in the 260s/870s and 270s/880s. Their composition is discussed in the article. They all belong to the period of the uprising of the muwallad landowner ʿUmar ibn Ḥafṣūn between 267/880-1 and 303/915- 6, against the Emirate of Cordoba.
