Observatorio 1873

Observatorio 1873 is a tourism park in Mazatlán, Sinaloa, Mexico. The site originally was constructed in the mid-19th century as a military lookout to defend the port against pirates and enemies. In 1873, it was converted into an observatory focused on meteorology and seismology, positioning it as one of the foremost institutions of its type in the Porfiriato era. After falling into disuse, the site was acquired by the businessman Amado Guzmán, who began renovations around 2017 and opened it as a tourist park on 21 March, 2021.
