The view southwards from the Torre dos Clerigos in Porto. Rising over 75 metres from what is already a high point in the city the views from the tower are pretty impressive, and may help you make sense of the haphazard layout of Porto.
From this vantage point the most notable building is the old Cadeia da Relação building. This was built as the city's court of appeal but is now home to the Portuguese Centre of Photography.
