Ecuador’s biggest city, Guayaquil is also the chief port and commercial center. A good starting point for sightseeing is the Rotonda, the city’s most historic landmark, which faces the beautiful garden promenade of Paseo de las Colonias. Across the malecón are the Government Palace and city hall while, at the northern end, one can find the ancient fortress of la Planchada. Other places of interest include the Church of Santo Domingo, the old residential section of Las Penas and the Municipal Museum.
