I received this postcard today...from Portugal.
The postcard shows an image of a photograph taken by Emílio Biel, (1838-1915).
He was a businessman, publisher, and photographer. He was considered one of the pioneers of photography in Portugal.
The subject of the photograph is Torre dos Clérigos, or Tower of Clergy [Church] in Porto, Portugal.
The Clérigos Church is a Baroque church which was built by Nicolau Nasoni, an Italian architect and painter. Construction of the church began in 1732 and was finished in 1750 (approximately).
The monumental bell tower of the church, Torres dos Clérigos, is located at the back of the building. It was built between 1754 and 1763 and is 75.6 meters high (approximately 248 feet high), dominating the city. This great structure is one of the most characteristic symbols of Porto.
