Europe Day has been going since the European Union's beginnings in 1950 and celebrates a continent with about 45 countries, 23 languages, 50 mountain ranges - as well as a clear cut-off point at Portugal but only a hazy boundary north towards Russia and east to Georgia.

Let us know how you got on in the comments below
