Seville is well connected to the world by an international airport, a high speed train, four motorways, and a river port, and contains the longest bycicle track system in Europe. Touristic attractions include historic district with the gothic Cathedral and the Arabic Palace Alcazar, Baroque churches, a theme park, river cruises, and nearby National Parks and beaches. Seville combines a rich historical past, when it was the main gate to Europe from the Americas, with a vibrant present as a technological center and meeting point.
