Rosana Guerra took part in the VII Semana da Historia de Noia  [Noia’s 7^th History Week] –her hometown–  with a talk about arches and vaults.

The talk began drawing the attention of the audience to the weight of the stones that form the vault. Then, she explained the mechanism of the arch, the normal cracking pattern and the different types of arches and vaults taking examples from the local churches and making use of several models to illustrate the explanations.

The talk finished loading with small sandbags a 3D printed arch until collapse.
