Also during this time and with the work of European landscapers in 1873, O'Higgins Park came into existence. The park, open to the public, became a landmark in Santiago due to its large gardens, lakes, and carriage trails. Other important buildings were opened during this era, such as the Teatro Municipal opera house, and the Club Hípico de Santiago. At the same time, the 1875 International Exposition was held in the grounds of the Quinta Normal.
