I recently had the opportunity to visit the famous "Gretna Green" blacksmith shop in Scotland.  The original anvil is now on display under glass.

Is there any blacksmithing being done there now, or is it just a "photo op"?

 

That "original anvil" certainly has taken a "beating".

It's fame was that in Scotland a consenting couple could "marry" themselves by reciting their vows in a public location before witnesses.  Unlike England where a license was required and parental permission for under age (under 21) persons.

 

So  Gretna Green was the first village over the border along a main posting road and the Blacksmith Shop was a central "public" place with built in witnesses and *that* is why it was famous...

 

Much like kids too young to marry in one state in the USA eloping to another that allowed them to marry.

As Thomas mentioned, it is right across the border of England.  It is nothing more then a tourist trap nowadays, complete with a tour bus of Japanese.  There are several other old English anvils in the 250lb range painted with the Gretna Green words in each of the rooms, a couple of old carriages and time period items.  I believe the tour to see the original anvil was around $10 USD.
