What is the most interesting city to visit in your country?

I like to visit Nuwara Eliya. This is my favorite place in Sri Lanka. This is beautiful hill station in the island. So guys, What is the most interesting city to visit in your country?

I love to visit Galle which I didn't visit yet. I love to visit coastal cities in Sri Lanka, they're breathtakingly beautiful with the ouline of ocean blue waters!
