The Black Sea destination, and the only one of the four where the sun sets into the water.
The ceremony here is set by the light over the water: the sunset is visible whole, with no mountains cutting off the last hour. So the timing of the day is counted from sunset rather than from a convenient slot in the schedule.
Because of the western longitude the sun sets here almost a quarter of an hour later than in Tbilisi, and the whole window of soft light shifts with it. The difference is small, but in a day tied to the light those minutes show.
Guests are brought in a day early: it is five to six hours from Tbilisi by road, or a domestic flight, and a journey that long does not fit into the day of the event.
