Museo El Rehilete, Interactive science museum in Pachuca, Mexico

Museo El Rehilete is a science museum in Pachuca whose main building is a 24-sided polygon with four levels arranged like an inverted mine. Architects Arturo Alcocer Martínez and Eduardo Romo de Vivar designed it; the complex covers about 15,000 m², with 12,700 m² built. Its ten thematic rooms include Energy, Light and Optics, Water with Science, Universe, and a planetarium.

The planetarium was built in 1993, four years before the museum, which opened on 28 February 1997 through the government of the state of Hidalgo. The observatory entered service on 5 January 1999, the archaeological walkway opened in 2000, the botanical garden began in 2001, and the Dinoparque opened on 23 November 2009.

The name "rehilete" refers to the pinwheel, a traditional toy that spins in Pachuca's strong winds, the reason the city is nicknamed "La Bella Airosa". The museum's ten thematic rooms include a maker space and a room on energy, and two murals decorate the grounds: "Municipio libre" at the entrance and Armando Peñafiel's 2014 "Ciencia, tecnología y los niños".

The building has four levels arranged like an inverted mine, with ten thematic rooms inside; the planetarium is a separate circular building 18 m across, ringed by a spiral staircase. The botanical garden covers 550 m² and the dinosaur park 9,000 m², so allow time to walk the grounds. The DC-3 aircraft, library and fire-station exhibit sit outdoors.

The outdoor grounds hold a DC-3 aircraft, a library and a fire-station-themed exhibit, alongside the Dinoparque opened on 23 November 2009. The Dinoparque covers 9,000 m² and displays two murals: "Municipio libre" at the entrance and "Ciencia, tecnología y los niños", inaugurated in 2014 and made by Armando Peñafiel.
