Housed in the former communist presidential palace, this museum occupies a stunning, if inconvenient, setting; unless a coach party turns up, you may have the place to yourself. The exhaustive collection includes Thracian gold treasures, Roman statuary, folk costumes, weaponry and icons, and outside you can see some Russian MiG fighters. There are regular temporary exhibitions, too.
