A monastery is like a special house where people live who want to spend most of their time praying and serving their religion. It's a bit like a big club where people who love the same things can go and hang out together.
Inside a monastery, there are usually different rooms for different purposes. There might be a big chapel or church where people can go and pray together. There might also be rooms where people can sleep, eat, and work on things like making clothes or growing vegetables.
The people who live in a monastery are usually called monks or nuns, depending on whether they're men or women. They take vows to give up certain things, like getting married or having a lot of fancy possessions, so they can focus on their religion and helping others.
Monks and nuns often wear special clothes, like long robes, to show that they're part of the monastery. They also might have special rules about things like when they wake up or what they can eat. Some monasteries are very strict, while others are a bit more relaxed.
Overall, a monastery is a place where people who love their religion can go to devote themselves to it with other like-minded individuals.
