About Asmara

Asmara rewards travelers interested in architecture, urban history, and everyday café culture. The modernist center, cinemas, churches, mosques, markets, and tree-lined avenues reflect the city's distinctive twentieth-century layers, while the highland setting makes it a cooler base than Eritrea's coast. Travel outside the capital requires planning and may involve permissions, so confirm current rules through official channels before arranging regional excursions. Ask before photographing people or government facilities, carry cash and practical supplies, and build flexibility around transport and opening hours.
