My dad retired to Morecambe, England.
They recently built a new sea wall to protect the town centre from waves in high winds, because the old one was crumbling..
Cost: £10 million.
They said it was supposed to be good for 100 years. It is only 3 cm higher than the old one. It only covers about a km.
It's not going to be 100 years before the sea goes over it and around it. The nearby smaller towns on the coast have nothing.
