🚨 Time for #fridaygeotrivia 🚨

Name capital city pairs (and their countries) that are less than 100km by land (no tiny islands) from each other. For example Vienna, Austria 🇦🇹 and Bratislava, Slovakia 🇸🇰

As always:
• Only one answer per toot
• You must include the hashtag #fridaygeotrivia and the emoji flag of relevant countries
