Did you know that Ljubljana is twinned with Tbilisi? No, neither did I.
You can see all the other places Tbilisi is twinned with here and here is the equivalent in that wonderful script that the Georgians have:
Ljubljana, Slovenia (1979) ლიუბლიანა, სლოვენია
It seems Tbilisi is also twinned with Bristol, though I can't think what they have in common.
Bristol, United Kingdom (1988) ბრისტოლი, გაერთიანებული სამეფო
