Echternach is a small town with about 5000 inhabitants on the eastern border of Luxembourg, just a hop away from Germany. It's Luxembourg's oldest town, based on an old monastery founded in 698.
The old abbey founded in 698 by St. Willibrord is one of the must-sees in Echternach. Today, it's a school building for high-school classes (7th-13th grade). The basilica next to it still serves as church of Echternach. If you're interested in the history of the monastery, there is a small but nice museum next to it.
The town square with its square cross and the historical guildhall "Denzelt" is a nice place to see and stay.
The roman villa about 20 minutes walk from the centre shows the remains of an ancient roman house. A walk-through is free, worth a visit.
The lake is an artificial lake. Enjoy the silence around it, 20 minutes walk from the city centre.
Macarons mous, typical traditional sweets. Taste like pure sugar, but at least you should give them a try. Can be bought at the Patisserie Zimmer and Patisserie Simon.
Most cafés are situated around the town square and the main shopping road
'Café de la Poste (Wohli)' offers a nice ambiance on two floors and a small terrace for summer evenings. Also got some minor fast-food.
Café 'Aal Eechternoach' is mainly nice because of its terrace directly on the town square.
'Café Philo'soff' is still an insider-tip. Typical students-pub in the main shopping road. Especially the garden is nice. Very crowded on Friday evenings
