Seville: romantic, lively, passionate and historical, and being located along a flat plain on the Guadalquivir River, the city is entirely walkable for a perfect day of exploration. Seville is the capital and largest city of the autonomous community of Andalusia. Its Old Town, with an area of 4 square kilometres (2 sq mi), contains three UNESCO World Heritage Sites: the Alcázar palace complex, the Cathedral and the General Archive of the Indies.
