Russian President Vladimir Putin is believed to have built himself a stunning new hideaway fit for a tsar, complete with a swimming pool with gold-plated tiles.
The lavish holiday home is away from prying eyes on a northern island just a few miles from Russia's border with the West.
The heavily guarded tsarist palace was once used in a 1987 Soviet film about Sherlock Holmes, and was linked to Putin by Russian media.
New 3D renderings supposedly show the interior of the restored 16,150 sq ft dacha, which was once a dilapidated estate.
They reveal a grandiose indoor pool, a steam sauna, a billiard room and study with the Russian double headed eagle emblem.
The mansion called Villa Sellgren is built on an island in the Vyborg Bay, around 12 miles from the Russia-Finland border.
Officially, it belongs to close friends of the president but locals say it is the latest prestige home in a stunning property portfolio rumoured to be Putin's.
Lodochny island and the sea around it is reported to be heavily guarded by Russian Federal Protection Service officers, preventing locals getting close.
The retreat was built before the Russian Revolution in 1913 by famous Finnish architect Uno Ullberg.
A source told independent TV Rain in Moscow: "After 2010 they started building a dacha for Putin there."
The rundown villa was renovated and either a massive extension has been added to the mansion, or a new separate home is built nearby, it is claimed.
Several other large houses have also appeared on the island.
Locals have posted complaints on the internet saying that previous access to the island has been banned and a helicopter pad installed.
There is "even a radar on the beach so that the enemy divers can't get through", according to one.
Another, called Alexander, wrote: "This is Putin's residence here."
He is believed to stay at least once a year at the property which is protected by a three-mile fence.
The 3D images and a floor plan were also posted online, an evident leak of construction plans for the holiday home.
They showed the swimming pool, part of an "underground spa", captioned using Putin's initials: "Here is where VVP bathes."
According to Alexander, Putin comes to the property once a year although no official announcement was ever made.
The land was switched some years ago from being protected forest to allow the development of a "resort".
Rus construction company - linked to the 3D images - refused to comment on the development.
Bosses of another company - Adis Group design bureau - failed to answer requests for information on the alleged Putin dacha from TV Rain.
Attempting to reach the mansion, security guards told TV Rain it was a "closed object" with no access.
Until 2014, the Sellgren complex officially belonged to the head of Baltic Media Group Oleg Rudnov, described as an "old Putin friend", who also once owned Lindstrem's dacha in St Petersburg, also now alleged to be Putin's.
Rudnov died in 2015, and his son Sergey inherited his empire including Sever company which officially owns the island properties linked by the media to Putin.
This latest alleged Putin villa is only 60 miles from another village complex where one home has a grass covered roof on the shore of Lake Ladoga in Karelia region.
He is also rumoured to own a palace on the Black Sea called Gelendzhik, and a dacha close to St Petersburg, and an Altai Mountains retreat officially belonging to Gazrom.
