The multi-storey Baroque building of three facades was extended following a continuous development pattern in a U-shape, embraces with two lateral wings a central courtyard and is cellared for the most part. The building has two main entrances, one facing Szentháromság steet and another facing Úri street. There is a corner balcony at each of the two corners of the building supported by ornamented stone posts, the windows are decorated with stone parapets ornamented with carved floral and garland elements, a pointed and a curved hood molding. The plate of the Eastern balcony is decorated with a lion’s head figure and the Western parapet with the coat of arms of Buda.
The reconstruction presented the simultaneous challenge of understanding and systematising the history of several centuries in related to the building – how the areas, walls and functional structures were built upon each other in successive phases across the various ages, and what was the logical sequence behind the successive extensions that lead to the present condition. The conclusions drawn from these questions have been incorporated into the architectural concept, which at the same time satisfies the contemporary technical and mechanical requirements.
There are few other historical monuments in the country that have been dedicated such an extensive archaeological and historical research as this building. The newly explored data, functional areas and monuments are displayed at the exhibition housed in the basement floor which is open to the public, and while visiting the exhibition the visitors may also see spaces where no one has laid foot since the times of the Ottoman Empire. We can observe the medieval network of streets, and the traces of the medieval alley at the spot where a building stands today and explore findings of art history reach and from the investigation of historical archives. We can say that an impressive material was compiled, which on one hand is relevant from a scientific aspect, but on the other it also provided specific knowledge of practical application for the restoration work.
The statue of Pallas Athena standing at the corner of Szentháromság street and Tárnok street became an evident part of the building in the 20th century. The legend that the goddesses’ spear was often stolen and needed regular replacement has become widely known owing to the television show of preservationist Mihály Ráday. The statue was renovated during the reconstructions, and now stands as a decorative element of the façade at her original place, true to her original appearance.
