A closer look at the Torre dos Clérigos (Tower of the clergymen). The tower is an icon of Porto and has six floors and is 75.6 m high. It has pretty much dominated the city's skyline since it was built in the 1760s. Technically this is the bell tower of the Clerigos church and even though the two were built at the same time and both designed by Nicolau Nasoni it does appear to be a bolted on addition.
It is said the tower was built to be so visible to appear as a "lighthouse of faith" hovering over the city.
