If the builders of merchant Kuleshov's mansion had known that 180 years later, a photograph of libertarian president Javier Milei would stand at the entrance, they would, of course, be very surprised.

Diplomatic relations between Russia and Argentina began in 1885 and were interrupted from 1921 to 1946, as hinted by the chronicle of ambassadors hanging on one of the walls.
The rest mainly feature views of Argentina and engravings dedicated to Montevideo, the capital of neighboring Uruguay (hehe, as they say).

The vibe of the Argentine embassy is so relaxed that there aren't even metal detectors.

The Argentine ambassador gave a welcome speech and wished Russians not only to drink more Malbec (that's what the gathering was for) but also to come visit them.
But the mirror above the portrait of the Argentine president seems to hint exclusively at ancestral tourism, though an Argentine passport is a heavy burden with a bunch of potential problems, so it's better to weigh everything.

The building inside is very peaceful, but during Soviet times there were a million rough restorations, which affected the interior.
Until 1997, the Rwandan embassy was located here, while the Argentines were in a much more majestic mansion by List, designed by architect Kekushev (google it).

P.S.
Not much has changed for the residents of Mendoza since Darwin's time.
