Meaning
The flag emoji for Saint Barthélemy, often shortened to St. Barts, a small island in the Caribbean that is an overseas part of France. It represents the island and its community.
It mostly appears in travel posts about white-sand beaches, sailing, yachts and French-Caribbean food: “Snorkelling in St. Barts 🇧🇱 the water is unreal” French is the main language there, so it pairs well with 🇫🇷 and 🏝️.
