Sanaa,[a][b] officially the Sanaa Municipality,[c] is the capital and largest city of Yemen. The city is the capital of the Sanaa Governorate but is not part of the governorate as it forms a separate administrative unit. According to the Yemeni constitution, Sanaa is the capital of the country,[3] although the seat of the Yemeni government moved to Aden, the former capital of South Yemen, in the aftermath of the Houthi occupation. Aden was declared the temporary capital by then-president Abdrabbuh Mansur Hadi in March 2015.[4] At an elevation of 2,300 metres (7,500 ft),[5] Sanaa is one of the highest capital cities in the world and is next to the Sarawat Mountains of Jabal An-Nabi Shu'ayb and Jabal Tiyal, considered to be the highest mountains in the Arabian Peninsula and one of the highest in the region. Sanaa has a population of approximately 3,292,497 (2023), making it Yemen's largest city.[6] As of 2020, the greater Sanaa urban area makes up about 10% of Yemen's total population.[7]
