Barcelona is in terms of twitter activity one of the cities that has a strong central core of high activity. Very similar to for example the London NCL or the Paris NCL maps.
The highest point is just over the Placa de Catalonia with a steep slope down la Rambla to the Roca Columbus. Other places of high activity are around the parliament, here the 'Monte di Parliament Catalonia' and around the Olympic centre on Montjuic.
The overall structures are also visible on the twitter map. The boundary of the sea on the souther side of the urban area and the hills and valleys in the northern part for example. Especially the vallies and how they flow into the centre of the city are reflected in the NCL map with fingers going out along these lines.

The Barcelona map was generated from just over 24'000 lat/long geo located tweets collected the week ending 100715. Those came out of a sample of over 250'000 'Barcelona' twitter messages. Thanks to Joan Serras for the help with the labeling.
