Don’t ask me how I got access.
When I was in Borjormi I managed to get into the grounds of the summer residence of the Georgian president, Mikhail Saakasvhili. The house was formerly occupied by Eduard Shevardnadze, and before Soviet times it was a Dacha of Tsar Nicholas II and the Romanov Dynasty.
The residence was where Saakashvili and his Ukrainian counterpart signed the Borjomi Declaration recently.
No photos of the interior I’m afraid – it was off limits.
