After his death the building was bought by his widow empress consort Elizabeth Alexeievna (Louise of Baden) and the first memorial museum in Russia dedicated to the Emperor was established there.

For 12 years beginning in 1864 an amateur choir conducted by Pavel Chekhov (Anton Chekhov's father) sang in the Church of Exaltation of the Cross, which was established within the mansion to honor the emperor.

At the end of 1860s – beginning of 1870s Alexander, Nicolas and Anton Chekhov sang there in choral parts of descant and alto.

In 1928 the memorial museum was closed and some of the exhibits were moved into the Alferaki Palace.

The building of the Palace of Alexander I houses a children’s sanatorium called “Beryozka”.
