They were built as defensive strongholds capable of withstanding external attack and keeping the people inside safe.

And we’ve only just shut the drawbridge.

The other fun bit is siege, the idea being you had enough supplies inside to withstand a prolonged attack.

Right now, we’re failing there too.
