The estate itself can already be seen on maps from the year 1921. The current main house is probably not that old, but old altogether. The balance between vandalism and the decay of time was somewhat in balance. See for yourselves:

The pump house was probably part of the water supply system for the Lielahti paper mill back in the day (visited, for example, in this post: https://raidsquad.blogspot.com/2006/04/kuvapivitys.html ). The mill itself is located right next to the lake, but apparently, even then, they realized that the water quality near the factory was terrible—it had to be pumped from further away. A small site in a beautiful spot, pretty trashed, but shown here in pictures:
Complex built in 1941, expanded in the 60s, renovated in the 90s. Left alone to decay in 2018. The site was sold to Russian buyers in 2022, but the sale was halted by the Finnish Defence Forces for obvious reasons. The real estate is on the verge of complete destruction—maybe still salvageable, maybe not. Anyway, the current state is now memorialized in digital form.
