Hi,

you are wrong thinking Leipzig being a small town. It is the biggest city in the federal state of Saxony and has well over half a million inhabitants.
A lot of things to see and visit !
Johann Sebastian Bach created most of his works there (visit his Thomanerkirche). The reunification process of Germany took place at the other beautiful church, Nikolaikirche, where the demonstrations in 1989 started. Walk around on the old ramparts of the medieval city and visit the Town Hall (Altes Rathaus) and admire the beautiful old houses of a once very rich city (the Leipzig Fairs). The main station is the biggest in Germany and worth a visit.
There are interesting museums, the famous Auerbachs Keller (where part of Goethe's Faust is playing) and a lot of passageways. Food at Auerbachs Keller is not sensational, but the atmosphere is.
Leipzig also has an airport and a famous zoo (for your kid).
Saxony has its own food specialities (Sauerbraten with dumplings made of potatoes) as well as its own cake specialities.
If you have a lot of time off, do not miss a trip to Dresden.
I am sure you will enjoy this beautiful city.
