Porta do Sol is Vigo’s centre point, the hinge that connects Vigo’s Old Town and the Ensanche, the city’s oldest areas. This is where you’ll find art foundations, cultural centres and the most modernmuseums in Vigo. One of the symbols of the city is located right on the imaginary line traced by the Porta do Sol: the sculpture of El Sireno (The Merman), by Francisco Leiro, is a metaphor of the union between man and the sea.
