Be ready for a different kind of attraction. Faro de Moncloa is a 110m communications tower that was built by the City Hall in 1992. It is in Moncloa district, right next to Complutense University as it is part of its Campus. The observation deck is 92m high and you get a perfect view of (https://www.spottedbylocals.com/madrid/?s=templo) and of (https://www.spottedbylocals.com/madrid/?s=Casa+de+Campo). It has a 180º view over Madrid, from Plaza Castilla to University Campus. There are also history banners inside explaining the most significant buildings, in case you need proper explanation. If that is not the case, then it is just fun to try and find your own building or neighborhood, your favorite park or the busy street that you have visited. And the pictures you can take from here, especially on a bright sunny day, are simply spectacular.
It is interesting to notice how much the original project has changed over the years; first, for security reasons, but also to make it a proper attraction for visitors. The ticket to visit the observation deck is only 3€ and you cannot be up there for more than 30 minutes, but it’s more than enough time to enjoy the panoramic view and landscape.
It was reopened to the public in 2015 so I’m guessing few people know it is possible to make a visit. I have seen very few tourists up here; mostly “madrileños” come to Faro de Moncloa, especially people that want to get a different view of the city.
