How Does a Medieval Castle Keep Its Warmth in Winter?

A medieval castle stays warm in winter by trapping heat inside, just like a cozy blanket around your body.

Walls act like thick blankets, the stone walls of a castle are really big and heavy, so they hold onto the warmth from the fire. When it’s cold outside, these walls keep the heat in, making the inside nice and toasty.

Inside the castle, there are big fires in fireplaces or hearth, like a giant version of your kitchen stove. The fire gives off lots of heat, which warms up the air and the stone walls around it. When you’re near the fire, it feels like being hugged by a warm blanket!

The windows, though, are like open curtains, they let cold air in if not covered. So, people would sometimes use thick curtains or even wool blankets over the windows to keep the warmth inside and block out the chilly wind.

That’s how a medieval castle keeps warm, by using big walls, fireplaces, and good old curtains!
