Palacio Postal

This place is definitely worth the visit, even if it's just to look around. It's like a Hogwarts building in the middle of Mexico City's downtown. Perfect for tourists, and it's a working building as well, so you could mail a postcard or buy some stamps!

Very beautiful place to visit. The architecture is impressive and you can visit also almost everything in it if you schedule your tour.

One of the most Instagrammable places in Mexico City. The building is absolutely stunning and it’s free to go inside and take pictures. Try to make it there before their closing time before seven since it’s very empty. The post office is still functional so it’s not like a museum or something.

A building of stunning architecture, but generally only a part of the ground floor is open to visitors. That said, it's worth a short visit and it's a good place to send some postcards (that you've bought elsewhere--most museums have pretty decent gift shops). That's about it though. When I was there, there were a few photos and some pieces about railways in Spain and Portugal. It's quite cool inside, so that's good.

Very beautiful! Worth a quick pop inside. There's even a small "museum" of sorts. Visiting here should only take 15-30 minutes depending on how many photos you take and if you chose to look at all of the artifacts in the museum.
