The construction of the convent in the current crossing of Mexico and Defensa streets started ten years later, but the works were stopped until 1737, when the purchase of a new plot for the construction site was decided, in the block now limited by San Martin, Viamonte and Reconquista streets and Avenida Cordoba.

17.- The Torre Mihanovich Tower - Hotel Sofitel
Those who remember by heart say that in 1929 Nicolas Mihanovich wanted to built the tallest building in Buenos Aires to watch the ships setting sail bound to Colonia, in Uruguay. Moreover, they also say that Mihanovich wanted the tower to be the first thing to attract the attention of passengers arriving to Buenos Aires port, due to its evocation of a lighthouse illuminating the Rio de la Plata River.
Rising above 841 Arroyo Street, the Mihanovich Tower was for a long time the tallest building in town with its 20 stories and height of 80 metres. However, its creators wanted the building to stand 95 metres high but the administration of that moment considered it excessive and dangerous. For this reason, 10 stories were taken away from the original project.
The construction shows an eclectic combination of styles, typical of the transition that Argentinean architecture was experiencing during those years. There are classic ornaments with Art Deco and first rationalism variations. All the obtained data shows that the Mihanovich Tower is the first building made out of reinforced concrete in Buenos Aires and one of the first with special partitions to hold sway against the b winds.
It was totally refurbished by the end of 2002, to give birth to the international chain hotel brand Sofitel Buenos Aires.
