An old building or place that's been damaged can be ruined.
When we say something is ruined, we usually mean it's not working or looking like it used to. We might use this word when talking about a project that didn't turn out as planned, or an event that got canceled at the last minute. For example, if you spent weeks building a treehouse and then a big storm came through and knocked it down, you could say your treehouse is ruined. This can also be used to describe something that's beyond repair, like an old car with a broken engine. The word 'ruined' can have different shades of meaning depending on the context: something might be partially damaged, or completely destroyed, but it always implies that something was valuable and is now not working as it should.
