Montserrat is the only place outside Ireland where St. Patrick's Day is a public holiday. Nicknamed the "Emerald Isle of the Caribbean" for its lush green hills and strong Irish heritage, arriving passports are even stamped with a shamrock.

Before the eruption, AIR Studios Montserrat hosted legendary recordings by the Rolling Stones, Dire Straits, Elton John + others.
