This photo was taken from Miradouro de Nossa Senhora do Monte near the district of Graça. It is said to be one of the less touristic viewpoints in Lisbon but is nonetheless one of the most charming and so we visited it during our stay in Lisbon. The difficult part was that it was located in one of the highest parts of Lisbon and so climbing it, whilst carrying our camera equipment was not an easy challenge.
