Shire (Middle-earth)
According to Tolkien, the Shire measured 40 leagues (193 km, 120 miles) from the Far Downs in the west to the Brandywine Bridge in the east, and 50 leagues (241 km, 150 miles) from the northern moors to the marshes in the south,  This is confirmed in an essay by Tolkien on translating The Lord of the Rings, where he describes the Shire as having an area of 18,000 square miles (47,000 km²).
