Sanaa

One of the oldest continuously inhabited cities in the world, with a history stretching back at least to the 5th century BC, Sanaa sits high in the Yemeni Mountains next to some of the tallest peaks in the Arabian Peninsula. Its Old City is a UNESCO World Heritage Site, distinguished by multi-storey buildings decorated with geometric patterns. Al-Saleh Mosque, the largest in Yemen, lies on the city's southern outskirts. Travellers should consult current safety guidance before planning any visit, as the city has been under Houthi control since 2015.
