A year after the opening, the number of exhibits increased severalfold thanks to valuable items saved from estates in the Tarussa, Meshchov, Kozesk districts of the Kaluga Province.
As of today, the museum holds 10,000 pieces of painting and graphic art, sculpture and applied art; more than 200 of them are permanently on display.
The paintings are both by Russian (Serov, Polenov, Makovsky) and Western-European artists: from Italian Baroque (Bernardo Strozzi, Giacinto Brandi) to the Flemish one (including Rubens).
