Located in the center of Europe, fought over by the English, French and Germans, and now the home of the European Union, NATO, the hundreds of international organizations spun off these two groups; Brussels is densely packed with "must visit" places for tourists. Getting her is a snap with high-speed rail, international airlines, and super highways to the North, South, East, and West. Yet, Brussels has retained its small town charm amid these cosmopolitan attractions. So, here is my recommendation for a few of the highlights.
Grand Place

The Grand Place, has been called Europe’s most
beautiful medieval square. Built in
the 13th century, The Grand Place served a the hub of commerce in Brussels; however, the French bombarded Brussels in 1695, leveling the Grand Place. Four years later the Guilds of Brussels rebuilt the Grand Place and now their Guild Buildings line the square. This beautiful square is now a UNESCO World Heritage Site.
Every
other year (2014) the Grand Place is
decked out in an amazing flower carpet, made up of 1 million begonias - an amazing sight.
Horta Museum
Horta Museum in Brussels is the house that Victor Horta built it for himself in
late 1890. It is an excellent example of architectural style that made
Horta one of Belgium's most respected architects and a thought leader in Art Nouveau style throughout Europe. It is a must see, since I love Art Nouveau. I was very impressed.
Atomium
Built in for the Worlds Fair in 1958, the Atomium is a cross between sculpture and architecture. Modeled after a crystallized molecule of iron magnified 150 thousand million times, it's primary purpose was to promote commerce; so, it should be no surprise that it contains exposition halls and a restaurant. Inside the Sculpture, escalators take visitors to expositions in the various spheres and the upper sphere houses a restaurant, Chez Adrienne (note the windows in the sphere).
Atomium is located near Mini-Europe Park which also has 1/25th replicas of famous attractions across Europe. It is near King Baudouin Stadium.
Saint Michael and Gudula Cathedral

Beautiful Gothic cathedral located at Treurenberg hill.
Is an amazing place to visit.
It's architecture is on par with Notre Dame in Paris. Is also is the home of a stunning stained glass window series, three scenes of the legend of the Miraculous Sacrament. Since the early 11th century there was a church
here. In 1047, Duke of Brabant, Lambert II, ordered that the relics of
Saint Gudula to be moved from St Gorik in downtown Brussels to the new
church on the hill Treurenberg. Since then St Michael and St Gudula
acquired a greater importance than any other church, Brussels.
City Hall Gothic Tower

When you enter the Grand Place your eyes can't miss the stunning architecture of the City Hall. Also gutted in the French bombardment of Brussels, it was rebuild over a period of 50 years and now has regained its original splendor.
A little secret. Be sure to visit inside this beautiful building. Here you will find a treasure trove of tapestries, sculptures and art that represent the local history and culture of Brussels.
The Chocolate Museum

You definitely have to go to the Chocolate Museum, it is amazing!!!
Even if you do not love chocolate, you will appreciated the work
.
You learn so much and see some incredible things like the pictures I placed for you to see here.
They are "ALL" made of chocolate. Incredible!
Then you can go and visit some of the Brussels’s most celebrated chocolate shops. Here is a few:
Wittamer
Located in
the heart of the city, this family-owned chocolatier has been in
business since 1910. It’s the official chocolate supplier to the Belgian
Court.
Pierre Marcoline
His flagship store is located near the Grand Place. Marcolini opened his first store in 1995, the same year he was named the World Champion of Pastry. So he is considered a new but amazing addition to the Belgian chocolate scene.
