Greater London is bordered by the ceremonial counties of Hertfordshire to the north, Essex to the north-east, Kent to the south-east, Surrey to the south, and Berkshire and Buckinghamshire to the west. The official London region is one of the nine in England, as well as one of the four that make up Southern England.
Middlesex is on the north bank of the River Thames, bounded on three sides by rivers, namely the Thames to the south, the Colne to the west (or leastwise its old course) and the Lea to the east.
Middlesex, historic county of southeastern England, incorporating central London north of the River Thames and surrounding areas to the north and west. Most of Middlesex, for administrative purposes, became part of Greater London in 1965. The River Thames was the key to the history of Middlesex.
The county's boundaries largely followed three rivers: the Thames in the south, the Lea to the east and the Colne to the west. A line of hills formed its northern boundary with Hertfordshire. The county was the second smallest of the historic counties of England, after Rutland.
