Pins — Bite-Sized Travel Facts

Did you know Slovenia has the world's largest cave castle? Predjama Castle has clung to a cliff face for over 800 years, built directly into a cavern mouth. Its most famous resident, the knight Erazem, withstood a year-long siege by smuggling food through secret cave tunnels — until a betrayal ended it rather abruptly.

Did you know french fries most likely come from Belgium? Villagers along the Meuse valley are said to have been frying potato strips centuries ago, and one story claims American WWI soldiers dubbed them "French" because their Belgian hosts spoke French. Belgians remain the masters: double-fried, in a paper cone, with mayonnaise.

Did you know the potato was first domesticated in the Peruvian Andes around 8,000 years ago — and Peru still grows over 4,000 native varieties? They come purple, red, yellow, knobbly and finger-shaped, many thriving only at specific altitudes. Andean markets sell kinds of potato most of the world has never seen.

Did you know salmon sushi came from Norway, not Japan? Until the 1980s the Japanese didn't eat raw salmon, fearing parasites. A Norwegian trade campaign convinced them their cold, farmed Atlantic salmon was safe and delicious — and salmon nigiri became a global staple.

Did you know Vietnam is the world's second-largest coffee exporter — and Hanoi's signature drink is egg coffee? Whipped egg yolk and condensed milk are beaten into a sweet, custard-like foam over strong coffee. It was invented in the 1940s when milk was scarce.
