evidence: Gibraltar: A Bite of Britain in Spain [...] By Rick StevesWhen in southern Spain, I can't resist popping into the British colony of Gibraltar. Gibraltar is hardly signposted in Spain, as if Spain wishes the British colony didn't exist. (Drivers follow highway signs to La Línea, the last Spanish town before the border.) But when you see that famous "Rock of Prudential" standing boldly above the sea, you know it's here to stay. The 30,000 people living along a 2.5-mile lip of land under the famous and strategic rock are happily English. And quirky Gibraltar is determinedly not Spanish. But while over 90 percent of its citizens chose to stay with Britain in a 2002 referendum, almost 96 percent chose to stay with the European Union during the 2016 Brexit referendum, showing the complicated position the colony faces going forward.
