In his written work, architect José García Bryce stood out as a historian of Peruvian architecture. JGB has bequeathed us several important publications of which this book gives an account. Among them I highlight "150 años de arquitectura peruana" (150 years of Peruvian architecture), which he published in the early 1960s in the bulletin of the defunct Society of Architects of Peru. This is, in my opinion, his main text, because it documents the so-called republican architecture, a period of transition between the colonial and the modern that, without the contribution of García Bryce, would have been forgotten. It is interesting to observe how all this correlate also serves to evaluate the relevance of a modern architecture in Peru, where García Bryce exercises, from the historical support, a vision.
