On 26 Feb 2018 Portugal released a set of 4 stamps and a souvenir sheet containing one stamp featuring views of the Tagus River (Rio Tejo). The fourth stamp in the set with a denomination of €0.65 shows the Lisbon Vessel Traffic Control Center in the background. I guess we could call it the Leaning Tower of Lisbon! To the left of the building we can see a red light which is the VTS Algés Pier Head Light.
