1. Mainau: An Island of Bliss
Situated in the center of Lake Konstanz, Mainau is a magical island with a fascinating past. For centuries, the island's palace was a center of the Teutonic Knights, before it passed through a string of aristocratic families. Nowadays, it's open to everyone, and it's a gem of an attraction. See the gorgeous arboretum featuring 500 species, the equally stunning Italian rose garden and, of course, the historic palace itself. Everything is accessible via a causeway, and it's not far from central Konstanz.
2. Konstanz Minster: A Sonic and Visual Delight
The city's graceful cathedral is its spiritual heart. Probably founded in the 7th century after Christ, it took its current form in the 16th century when an army of craftsmen turned it into a Gothic masterpiece. Be sure to venture inside to see the elegant decorations and the soaring vaulting, and take in the views from the Observation Tower, too. If you can spare the time, hang around to hear the bells chime the hour; with Germany's second largest collection of bells, the sound is quite something.
3. Konstanz Hafen: Lovely Views in a Historic Location
The city's harbor was once a key node in European trade, coordinating the movement of goods between Italy and the Holy Roman Empire. You can get a feel for these glory days at the beautiful 14th-century Council Building, which is still used for official purposes. Wandering around the harbor is a delight, with sublime lakefront views. You'll also stumble upon a monument to Ferdinand von Zeppelin, the inventor of the airship, as well as plenty of green space to relax and enjoy the sunset.
4. SEA LIFE Konstanz: A World of Watery Wonders
SEA LIFE is a world-class aquarium which reflects Konstanz's obsession with water. Located right next to the lake, it hosts over 3,500 marine animals -- a mixture of salt and freshwater creatures. Feeding time is a highlight, as the turtles and sharks receive their treats, but it's always rewarding to wander the corridors and get to know the locals. Don't miss the Nemo-style clownfish and the ghost-like jellyfish as well as the fearsome sharks and the languid sea turtles. There's even a cute penguin colony to round off this family-friendly assortment of sea-dwellers.
5. Imperia: An Iconic Figure with a Controversial Story to Tell
Standing proud at the center of the harbor district, Imperia is the most famous symbol of modern Konstanz, and getting a snap with her is a vacation essential when you visit the city. Created by controversial German sculptor Peter Lenk, Imperia commemorates a famous moment in the city's history: the 15th-century Council of Constance. Nine meters tall and rotating at a rate of one turn every four minutes, Imperia balances imperial and Papal power in her two hands. Apparently based on a story by Balzac, the real Imperia sought to seduce Popes and emperors -- giving the statue a complex, provocative double meaning.
6. Bodensee: Lake Constance Sports
Bodensee, or Lake Constance, situated on the Rhine beneath the Alps is comprised of the Obersee - Upper Lake Constance, the Untersee - Lower Lake Constance, and the Seerhein, which connects the lake to the Rhine. Bodensee is bordered by Germany, Switzerland and Austria. The lake has become a tourist destination as a result of its sports attractions, which include swimming, sailing, and boating. It is also possible to bike the 162 miles around the lake on the Bodensee-Radweg trail.
