Okay, so there is a special place called the Chapel of the Milk Grotto, and it's a really important place for some people. It's a small church where people go to pray and feel close to God.
The reason it's called the Milk Grotto is because there's a story that says a long time ago, a lady named Mary and her baby Jesus were hiding in a cave, and she accidentally spilled some of her milk on the ground. But then a miracle happened – the milk turned the stone of the cave a really pretty white color!
So people started going to this cave to see the white stone, and they believed that it had special powers to help women who were trying to have a baby or who needed help with breastfeeding. It became a really popular place for women to go and pray for help.
Eventually, they built a chapel around the cave to make it more special and comfortable for people to pray in. And that's what the Chapel of the Milk Grotto is – a special church built around a cave where a miracle happened, and where people go to feel close to God and ask for help.
