Student thesis: Master's Thesis


This dissertation aims to present the study of the skylights in the Historic Center of Porto´s houses, namely the Bourgeois Mercantilist House. The skylight is an iconographic element of Porto´s historic houses, appearing in many different shapes on the city´s roofs and acting as the main source of lighting and internal ventilation in these narrow and tall buildings. The work present these structures through a strand of mischaracterization, by pointing out the skylights that are somehow different from their original shape and form in the city´s roofs. The study brings an updated overview of heritage safeguard by addressing the constructive system of the skylights, the variety found in the historic center and the anomalies most common in these structures that lead to a mischaracterization. From this analysis it´s possible to identify and characterize the changes currently suffered by the typical Porto´s skylights. A survey was carried throughout the area to identify, typify and quantify these structures that no longer appear in their original form, followed by a more detailed analysis in a smaller chosen area within the PHC. The historic center´s skylights tipologies survey and the uncharacterized skylights inventory elaborated in this work are intended to help preserve these structures included, not only in the historic center´s built heritage, but of the entire city of Porto.
