Here you will find the Pavilion Mies van der Rohe on the map of Barcelona. Similarly, we have other places (buildings, museums, parks, districts, etc.) on the map.
You can see the Torre Agbar on a road map with the street names and metro stations and of course the attractions. You also can see the city as a satellite photo. Also a combination of road map and satellite photo is possible. Zoom in the map for a more detailed view.
Tips for using the city maps on Barcelona.de you can find on the side "Help to the City maps".
