Okay kiddo, so the Hill of Crosses is a big hill in Lithuania where people put lots and lots of crosses. Like, thousands of them!
People have been putting crosses on this hill for over 200 years, and nobody knows exactly why they started doing it. Some people think it started as a way for people to show their love for their country and their religion. Others think it might have been a way to remember loved ones who had died.
Nowadays, people still go to the Hill of Crosses to add more crosses. Some of them are big, some are small, and some are really fancy. Some people also go to the hill to say prayers, light candles, or just take pictures.
It's a really special place for the people of Lithuania, and it even attracts visitors from all around the world. That's because the Hill of Crosses is a symbol of hope and faith, and it shows that even when things seem tough, people can still come together to create something beautiful.
