Grenada is widely known as the 'Spice Island' because it is one of the world's largest producers of nutmeg and mace, which even appear on the national flag. Its capital, St. George's, is frequently cited as the most beautiful harbor town in the Caribbean. The city is built on the steep slopes of a horseshoe-shaped volcanic crater that opens into a deep-water harbor known as the Carenage. The architecture is a colorful mix of colonial-style houses with red-tiled roofs and historic brick warehouses. St. George's is also home to Fort George, built by the French in 1705, which offers a 360-degree view of the island. Beyond its aesthetics, Grenada has a significant place in 20th-century history due to the 1983 U.S.-led invasion following a military coup. Today, the island is a peaceful destination known for its lush rainforests, waterfalls, and the world's first underwater sculpture park, located just off the coast of the capital.
