The Wikipedia article on condominium (in the meaning of joint sovereignty) lists a number of present condominiums, including Brčko District, which has almost 90000 inhabitants and is a condominimum between the Republika Srpska and the Federation of Bosnia and Herzegovina. It's probably not a major tourist destination, at least the railway station of Brčko town is rather small:
Wikipedia reports that the station is served by one train per day.
The Wikipedia article on condominium also lists Hadf as a condominium between Oman and the Emirati state of Ajman, but the Wikipedia article on Hadf lists it as simply lying in Oman. All other condominia listed by Wikipedia are either water or islets that are tiny, remote, or both. However, the list on Wikipedia may be incomplete.
Are there any inhabited condominiums (in the meaning of a joint sovereignty) besides Brčko?
To qualify for my question, a condominium need not be shared by separate nations, but sub-national entities, such is the case for Brčko, also qualify.
