He was the youngest son of Abram Abramovich Morozov and his wife Varvara Alekseevna Morozova.
Here he stayed on into the seventh year (1891-1892) in the mechanical and technical department.
Here he met Viktor Mazyrin who was responsible for the Imperial Russian pavilion.
Mazyrin had already been engaged by other members of the Morozov family, and Arseny told him that he was interested in having a mansion built in Moscow.
The Neo-Manueline mansion, inspired in the Pena Palace in Sintra, was designed by Viktor Mazyrin for his friend Arseny Morozov after the pair have toured around Portugal.
