Day Trip to Leiden - Rijksmuseum, Hortus Botanicus & more

I first heard of Leiden thanks to Leiden Copper Plates (detailed explanation on a Twitter thread). When I came to know that Leiden can be easily reached from Brussels by train, I thought, why not? So here's my day trip to Leiden from Brussels just in time to visit the Byblos exhibition there. However, I did miss too much, so when you plan, ideally go on a weekend trip to Leiden. Thanks to Leiden University, the town has a very youthful vibe to it. So, read on, to know how I spent my rainy day in Leiden.
