The Islamic occupation of the Iberian Peninsula shaped Portugal's art. During this time, Lisbon enjoyed a privileged position within the Gharb al-Andalus. When al-Andalus broke down into different taifas, or kingdoms, Lisbon fell under the taifa of Badajoz. The region of Sintra belonged to the taifa of Balata, and the town of Sintra, a medley of narrow, steep streets and alleys, had two strongholds: the Moorish Castle atop the hill, and a second fortification at the foot of the hill, where the walis, the governors of the city, lived. Sintra was a rabad al-Hisn, meaning a city without defensive walls. With the Reconquista, which brought Christian forces closer to Lisbon, Sintra became an important stronghold, yet al-Andalus left a lasting impact still visible today in Sintra's dense urban plan and colourful ceramic tiles.
