Yebes Observatory

Yebes Observatory is a radio astronomy research facility in Castilla-La Mancha hosting two radio telescopes. The site sits at 931 meters elevation and includes modern receiver systems and maintenance equipment.

Construction of the site took place between 1999 and 2007, with the German company MAN Technologie overseeing the main telescope structure. This period marked the birth of a modern research facility on the Spanish plateau.

The facility participates in global research networks studying space and Earth measurement. Its operations connect Spain with international scientific communities working on these shared questions.

Visiting requires advance planning since the facility operates primarily for research and is not open daily to the public. It is wise to contact the staff ahead of time to ask about access options and possible guided tours.

The site includes an anechoic chamber for high-frequency testing and a gravimetry pavilion enabling precise geodetic measurements. These specialized facilities provide measurement precision available at only a few other European locations.
