The observatorio Mohon del Trigo is an observatory, which was built in in 1902 and contained a 32 cm Cassegrain type KYOTO reflector telescope donated by Georgetown University. It is located in the vicinity of Pico del Veleta (3394m) in the Sierra Nevada mountain range in Spain at a height of about 2600m. The observatory was abandoned in the 1970s and deterioated into a ruin as documented by me in 2010. Since then, the observatory has been restored and is today in good shape (as seen from the outside, at least, I have not been inside). Nearby is also barracks used by the Special Operations Command of Spain. Here, the observatory is seen in evening sun as viewed from nearby Monument of Our Lady of the Snows. From this view point, the modern Sierra Nevada Observatory established 1981 can also be seen, but in the opposite direction.(Thanks to Slaunger for his excellent caption of his Featured Picture of the same building, I've almost copied and pasted...
