She made an alliance with the Zakarian dynasty of Northern Armenia
Located in the south, almost on the border with Turkey, Akhaltsikhe is dominated by an old fort, the Rabati, that towers over the city. The Rabati can be visited and it's a nice hike up the mountain. You get great views over the city and the surrounding hills. The museum closes at three - or so we were told. The fort houses a mosque and a ruined medressa. There is also a military hospital you are not allowed to visit.
Akhaltsikhe is a good starting point for visiting Vardzia with direct minibuses going that way, the last one leaving at 5.30 pm. There are also links with Borjomi and Khashuri - and from there to Tbilisi.
