Geometrical and constructive analysis of the choir and crossing timber frames of the church of St. María (Alaejos, Valladolid)

Abstract

This article presents a geometrical and constructive analysis of two significant carpentry works in the church of Santa María (Alaejos, Valladolid): the choir platform and the coffered ceiling of the transept. Both timber frames belong to the same historical period (between the 16th and 17th centuries), and have similar construction solutions, so they could have been probably made by the same author. The research was focused on the several pieces that configure these carpentry works. A design and construction hypothesis was then developed, including both the structural elements and some decorative elements, such as the muqarnas. This was done through a survey carried out with a laser scanner, which has provided us with an accurate 3D model. This study aims to deepen the knowledge of these carpentry works. We also provide graphic and written descriptions of both their current state and hypothetical internal configuration, which we believe could be useful for future conservation work.
