Restorations can happen, if there's enough time, money, interest, and energy.
On a much smaller scale, a number of volunteers (myself among them), under the auspices of county rangers, have been gradually restoring the grounds of Arden, the former estate of Madame Helena Modjeska, located in the Southern California foothills. Modjeska was one of the world's great actresses in the 1870s-1890s, second only to the more flamboyant Sarah Bernhardt. She came to the United States in part to escape the censorship being imposed in her native Poland, coincidentally by the governing Tsarist regime. :-/
Although many trees have taken over the estate since Modjeska was in residence, we are working toward restoring her rose gardens--using the same rose varieties from 100+ years ago!--as well as restoring the grounds in various other ways. I admit that while working outside amongst the California oaks, I have thought often of the Romanovs and their gardening activities that spring and summer of 1917.
