This was one of a couple of monster pots being used as gate guardians in Murcia, imposing to say the least. How do they turn a pot like that? They're bloody massive, just think of the weight of the clay alone.
The one above was taken while I was looking up at it and the one below, well, it's either an alien space craft or a mis-placed shell from Saddam Hussein's super gun. On the other hand just think about the amount of wine you could keep in there. Start the JCB up and dig a huge hole, get the pot in the hole somehow with sand all round it to keep it stable and fill it with Rioja.
Then you just work your way through it, and that works for me.
Just don't fall in when filling your glass.
