Nearest capitals

Distances are great-circle distances between city centres, which is what the Capitals game measures when it tells you how far a guess was from the answer. Dublin is the closest capital to Reykjavik.

How to remember it

Reading a figure once rarely fixes it in memory. Attach Reykjavik to a place and a number you already know: it is 1,495 km from Dublin, and it is the 156th largest capital in the atlas. Then practise retrieving it. DailyGeo Capitals gives you one mystery capital a day with distance, direction, language and population clues, the memorising method explains the review schedule, and the capitals index lists all 172.
