White Cliffs of Dover
Fish and Chips
Toby Jugs
Morris Dancing
Fox Hunting
St Pauls Cathedral
Cross of St George
Pint of Bitter
Red Telephone Boxes (sadly now gone)
Black Cabs
Cobbled Streets
Red Pillar Boxes
The Lark Ascending

Yes I know a few of these apply equally to Britain as a whole, but I'm sure you get my drift

Cheers
