The Caldeiroa Street (Portuguese: Rua da Caldeiroa) is a very important street in the Portuguese city of Guimarães, since it once had a huge part of the city's industry and factories.

[1] Along its route there are many notable architectural and cultural testimonies of the past: The first mention to this street dates to 1265.

[8] A strip of paper in archaic Portuguese from 1445 also mentions the street: "Rua Caldeiroa, de uma casa latada, anno 1445", which means “Caldeiroa Street, from a large house, year 1445”.

[9] In the 1890s, the Caldeiroa Street's floor was rebuilt with the extra stone that resulted from the demolition of the old church of S. Sebastião, whose bell tower was transplanted to the parish church of Creixomil.

In 1943, the city council once again made the historic name of this old street official, bringing back the name Caldeiroa once more.
