1. Owing to a bug in the 1974 Land Boundary Agreement between India and Bangladesh, there exists an infinitely recursive enclave 30km South of Cooch Behar: i.e., an area of Indian territory surrounding an area of Bangladeshi territory surrounding an area of Indian territory surrounding an area of Bangladeshi territory et cetera. The central few metres of this area have been repurposed to provide a temporary refuge for people who have been declared stateless, including a small centre for international law advice.
2. A 1888 attempt to stimulate patriotism by redrawing the boundaries of British counties so that each more closely resembled the letters in the phrase ‘God save the Queen’ was, surprisingly, only defeated in parliament by a single vote. This unusual happening has been attributed by historians to the flash outbreak of a food-borne fungal infection. Embarrassed legislators subsequently struck the episode from official records, although some reference to it can still be found in the newspapers of the era.
3. Portugal has never given up its claim to the entire continent of Antarctica, which dates back to the report by Henry the Navigator of having have been gifted a land in the far South by Prester John. In order that this claim not be invalidated under Portugal’s 1976 constitution, the state defines the municipality of Rio Prateado, a theoretical microcity with zero population in Adelie land. The exact location of Rio Prateado is highly classified, to avoid anyone else sticking a flag in it.
4. Under a 1630 law that has never been repealed, the summit region of any English or Welsh mountain is assumed to be part of the high seas for legal purposes. This led to the practice of holding duels on mountaintops, a practice that was still current in 1925 when Aleister Crowley was killed in a duel at the summit of Cader Idris and subsequently had to be resurrected by his Thelemite seconds. In order to perform the resurrection, they were obliged to offer Crowley’s digestive system as a home for lost ghosts, leaving him plagued with supernatural indigestion for the rest of his days.
5. As part of an abandoned weapons program in the mid-1980s, the entire island of Saint Helena was fitted with rockets, enabling it to take off from the South Atlantic, fly North and East, and land on Moscow, should the need arise. These rockets were never removed. Owing to the danger of accidental firings resulting from loud noises or strong vibration, every resident of Saint Helena is required to sign an agreement prohibiting them from playing music above a given volume. This is also the real reason that the recently constructed airport has been indefinitely put out of use.
