you can get married at all sorts of locations in Scotland - some really cool like the vaults under Edinburgh and in all sorts of buildings. As it happens we got married at Stirling Castle and had full run of the place which was a great laugh, she didn't like the idea of getting wedding photos straddling the huge cannons. I thought it would be funny. she not.
You may be aware - Scotland is due to have a referendum in 2014 to become an independent country and leave the rest of the UK. Whilst Scotland has it's own parliament and is a "country" - it is still controlled by a "union of parliaments" by Westminster, London. If Scotland votes yes then Scotland will be able to finance herself and make her own decisions. One of the key plans is to have a written constitution, although we helped write the USA's constitution, we were never allowed to have one by the UK. Scottish attitudes towards the human rights convention and the EU in general are quite different to that of the UK.
It is worth noting that there is a massive campaign of hate from the Unionist (i.e. "British") entities in Scotland which includes the state broadcaster. Scotland gets endless documentaries on "why Britain is great" etc and the BBC is heavily biased towards the Union.
