What Makes a ‘Famous’ Painting Last for Centuries?

Famous paintings last for centuries because they use strong materials and are kept in special places. Imagine a painting like The Mona Lisa, it’s been around since the 16th century, but it still looks amazing today. That's because she was painted on a thick wooden board called a panel, which doesn’t break easily. Also, people keep her in a cool, dark room to protect her from light and heat. It's like how you wrap your favorite toy in bubble wrap when you're moving houses, it helps it stay safe.
