I ¨C Em torno do porto de Colares %A Marco Oliveira Borges %J Revista da Faculdade de Letras : Historia %D 2012 %I Universidade do Porto %X In this study we will mostly focus on the coastal defence developed from Sintra during the Islamic occupation of the Iberian Peninsula, certainly intensified after the Viking attack of 844. However, special attention will be given to the Colares River to try to understand if it has ever operated as a port to the Muslim population of Sintra before its siltation. %K Sintra %K Vikings %K Coastal defence %K Port of Colares %U http://ler.letras.up.pt/uploads/ficheiros/11320.pdf
