The long triangular La Alameda is located at the beginning of street Guayaquil, where the historic centre begins. It has an impressive monument of Simón Bolívar at the apex. There are several other interesting monuments in this park. In the centre of the park is the Quito Observatory, which was opened by President García Moreno in 1873. It is used for both meteorology and astronomy. At the north end of the park are two ornamental lakes, where rowboats can be rented.
