Timelapse: Cloudy sky over the melted Shali Fortress of Siwa Oasis - Vídeo de stock 4K

Timelapse: A cloudy day is not usual in the sunny Siwa Oasis. Clouds fly over the Shali Fortress with the melted appearance which came as a result of a three-day rainstorm in 1926 that caused many of the buildings to collapse. The damaged houses are made from the traditional building material named "Kershif", or salt and mud brick and they are constructed of split palm-trunk roofs and earthen floors. This traditional building technique is a typical sample of spontaneous Organic Architecture.
