Structural and historical assessment of the 17th century purlin roof in the house n. 414/I in Prague old town

Research output: ThesisMaster's Thesis


The thesis analyses the timber roof of the 14C house once called “Three feathers” or “Wolf’s Throat”, in the historical center of Prague. The structure and typology of the roof were modified in the 17C by an italian architect, Martino Allio, who reused some medieval timber elements. The timber elements were partly dated thanks to a dendrochronological analysis. A geometric reconstruction of the prior medieval roof was carried out using the measured dislocation of the old joints still visible in the medieval elements. Present conditions of the structure were assessed using in-situ NDT and MDT, leading to the proposal of possible options for its repair and restoration.
