region was not situated in Lhasa. However, the importance of Lhasa as a religious site became increasingly significant as the centuries progressed. It was known as the centre of Tibet where Padmasambhava magically pinned down the earth demoness and built the foundation of the Jokhang Temple over her heart. Islam has been present since the 11th century in what is considered to have always been a monolithically Buddhist culture. Two Tibetan Muslim communities have lived in Lhasa with distinct homes, food and clothing, language, education, trade and traditional herbal medicine.
By the 15th century, the city of Lhasa had risen to prominence following the founding of three large Gelugpa monasteries by Je Tsongkhapa and his disciples. The three monasteries are Ganden, Sera and Drepung which were built as part of the puritanical Buddhist revival in Tibet. The scholarly achievements and political know-how of this Gelugpa Lineage eventually pushed Lhasa once more to centre stage.
The fifth Dalai Lama, Lobsang Gyatso (1617–1682), unified Tibet and, in 1642, moved the centre of his administration to Lhasa, which thereafter became both the religious and political capital. In 1645, the reconstruction of the Potala Palace began on Red Hill. In 1648, the Potrang Karpo (White Palace) of the Potala was completed, and the Potala was used as a winter palace by the Dalai Lama from that time onwards. The Potrang Marpo (Red Palace) was added between 1690 and 1694.The name Potala is derived from Mount Potalaka, the mythical abode of the Dalai Lama's divine prototype, the Bodhisattva Avalokiteśvara. The Jokhang Temple was also greatly expanded around this time. Although some wooden carvings and lintels of the Jokhang Temple date to the 7th century, the oldest of Lhasa's extant buildings, such as within the Potala Palace, the Jokhang and some of the monasteries and properties in the Old Quarter date to this second flowering in Lhasa's history
