Análisis constructivo de la cúpula de madera del desaparecido Palacio de los Cárdenas en Torrijos (S. XV)

In the National Archaeological Museum there is one of the four wooden ceilings with interlaced joinery that existed in the towers of the disappeared and plundered Cardenas Palace in Torrijos (Toledo, XVth C.), that was the only one with dome form. The exceptionality of this kind of domes in the Spanish joinery made each one of them a unique example. Knowing how to draw them allowed to reach the highest degree of the guild. However, in the treatises, a correct definition of the procedures for its layout, construction and integration of the interlaced pattern is not completed. After the in situ analysis of this timber frame we develop both its formal description and its constructive configuration; we reveal what is its resistant structure and we advance in the procedures that could be followed both for the introduction of the interlaced pattern in the difficult spherical geometry, and for carrying out its manufacture and assembly.
