20 years ago yesterday saw the final fall of the Berlin wall as loads of mad Germans attacked the structure with lump hammers and chisels in a bid to escape to the soviet bloc in search of much longed for freedom.
Probably less well known, yet no less momentous, the 10th of November marks the 20th anniversary of the collapse of a self built wall by Blodwyn Mawr of Wrexham.
Mr Mawr decided to build an ornamental five course wall in his back garden without the benefit of expert tuition. The result was a disaster.
On the 10th November 1989, the Mawr family's garden wall collapsed, as if in sympathy with its Berlin counterpart. But it wasn't a political issue.
"Her just fell down isn'it" Blodwyn told us. "It was my fault. I didn't know how to mix mortar properly, and I didn't know you used string and stuff to keep it straight. With hindsight, it were a bit pissed wasn'it, and there was only one way that wall was going Bach, and that was over.
"And it did. Didn'it?"
Mrs Mawr told us that she almost shat her nightie when the wall came tumbling down in the middle of the night with an almighty crash.
"I should have taken bricklaying lessons," Blodwyn added ruefully.
More as we get it.
