[en] This research demonstrates that the current Casas Reais street owes its name to a complex of buildings in which the crown of Castile established the first permanent home of the Audience of the Kingdom of Galicia in the early sixteenth century in Santiago de Compostela and that was fully operational in 1511. The graphical study describes the complex of buildings that hosted the institution and reconstructs their evolution between 1480 and 1920. Historical analysis has made it possible to relate all the different uses that resided in the Royal Houses throughout the history time providing abundant new information on each of its tenants and prominently licensed Feijoo, Gabriel Soto and Francisca Tapia, O'Sullivan Bear and the Jesuits, Maria de Cores and renters of the accessorial houses, the Brotherhood of the Souls, the Amarante palace, the Savings Monte de Piedad, the Economic Society of Friends of the Country, Simeon stores, etc. The graphic reconstruction technique has made possible to identify the original physical structure of such constructions: A complex covering an area of 2.750m2 formed by buildings, courtyards and gardens, who chaired an open square to the Camino road, which was self-sufficient and functionally autonomous; and that was articulated around two separate courtyards that made possible a constellation of houses around then. The investigation has established four different stages: the first one runs over the sixteenth century and is characterized by unity and autonomy of the complex; The second stage is related to the first half of the seventeenth century and, during it, the complex is divided in two separate parts; The third phase covers the second half of the seventeenth century and the whole eighteenth century. During this time the complete disintegration of the complex occurs. The Royal Houses became to be formed by a main house and up to 25 accessorial houses; Finally, between 1782 and 1920 the plot is recomposed to form several separated pieces with different uses. The research provides an abundance of unpublished documents whose transcripts are attached to the end.

[gl] A presente investigación demostra que a actual Rúa de Casas Reáis debe o seu Nome a un complexo de edificacións nas que a coroa de Castela estableceu a primeira sede estable da Audiencia do Reino de Galicia a principios do século XVI en Santiago de Compostela e que era plenamente operativa no ano 1511. O estudo describe gráficamente o complexo de edificacións que acolleu dita institución e reconstrúe a sua evolución entre 1480 e 1920. A análise histórica fixo posible relacionar a totalidade de usos que residiron nas Casas Reais ao longo da sua historia aportándose abundante información inédita sobre cada un dos seus inquilinos e destacadamente sobre o licenciado Feijoo, Gabriel de Soto e Francisca de Tapia, O´Sullivan Bear e os xesuitas, María de Cores e os inquilinos das casas accesorias, a Cofradía de Ánimas, o Pazo de Amarante, a Caixa de Aforros Monte de Piedade, a Sociedade Económica de Amigos do País, os Almacéns Simeón, etc. A técnica da reconstrucción gráfica fixo posible identificar a estructura física orixinal das devantidas construccións: Un complexo que abarcou unha superficie aproximada de 2.750m2 entre construccións, patios e hortas, que presidía unha praza aberta cara á Rúa do Camiño, que se autoabastecía e era funcionalmente autónomo; e que se articulaba ao redor de dous patios independentes dispoñendo dunha constelación de casas na sua contorna. Na investigación establecéronse catro etapas claramente diferenciadas. A primeira caracterizada pola unidade e autonomía do complexo prolóngase durante o século XVI. A segunda etapa desenvólvese na primeira metade do siglo XVII e nela ten lugar a fragmentación do complexo en duas pezas independentes. A terceira etapa prolóngase durante a segunda metade do XVII e todo o século XVIII e no seu transcurso prodúcese a máis completa disgregación do conxunto que se configura como unha casa principal e hasta 25 casas accesorias. Finalmente, entre 1782 e 1920 o parcelario recomponse formando varias pezas independentes dentro das que se agrupan as diferentes unidades en que quedou reducida a traza orixinal das Casas Reais. A investigación aporta unha abundante cantidade de documentos inéditos cuxas transcripcións adxúntanse cara ó final da mesma.
