2 Best Sights in Brussels, Belgium

Belgium's national botanic garden is a sprawling site that takes up most of the southern fringes of Meise. It wraps the old estate of Kasteel van Bouchou, which, despite being utterly destroyed during the French Revolution, was later rebuilt and now houses a museum all about the grounds. Beyond its moat lies an English-style garden filled with exotic plants from around the world, but the pièce de résistance here is the Plant Palace, the largest greenhouse in Belgium and one of the biggest in Europe. It is a vast biome of 35 hothouses filled with huge water-lily pads and tropical wonders. Other sights, such as the much smaller, mid-19th-century Balat Greenhouse, which was originally intended for a zoo, are just as fascinating for those interested. In addition, you'll find medieval, medicinal, and rose gardens, rhododendron woods, trails, art, an apiary, and some 18,000 plant species. Visit any time, though spring is naturally the most colorful season.  

Laeken is where you'll find the Royal Greenhouses, a glorious mid-19th-century mesh of steel and glass set within the grounds of the summer palace, where the Belgian royal family spends most of their time. It's only open to visitors for three weeks every spring (between April and May), but it's worth catching. The height of its winter garden, designed by Alphonse Balat, made it possible to plant palm trees for the first time in Belgium; the originals still stand here.
