Yes, but I think it's a mock-up and not a real Buran. It was mostly empty inside (and dark!). They showed us the hanger which partially collapsed and damaged the Buran inside, as we were being driven along.

While not quite the real deal, the aerodynamic test vehicle OK-GLI is at the Technik Museum Speyer in the same-named German City, open to the public (the nearby (30min; car) museum in Sinzheim has a both the french and soviet supersonic passenger planes (Concorde/Tu-144) in it's exhibit).

I can recommend both museums (interests have to match, of course).
