"OLDEST TOWN in LUXEMBOURG" a Echternach Travel Page by ViajesdelMundo

We made a day-trip from Germany and thoroughly enjoyed the old little town, with lots of shops and eating places in addition to the architecture.

There were a couple lovely looking hotels but I did not note them down.

Here is some info from WIKIPEDIA:
It grew around the walls of the Abbey of Echternach, which was founded in 698 by St. Willibrord, an English monk of Ripon, who became the first bishop of Utrecht and worked to Christianize the Frisians. As bishop, he directed the monastery as abbot until his death in 739. It is in his honour that the dancing procession takes place annually on Whit Tuesday.

The River Sauer that flows past the town now forms the border between Luxembourg and Germany, but in the later Roman Empire and under the Merovingians this was not a marcher land at all. The Roman villa at Echternach (traces of it were rediscovered in 1975) which was part of the see of Trier (now in Germany) was presented to Willibrord by Irmina (Irmine), daughter of Dagobert II, king of the Franks. Other parts of the Merovingian's Roman inheritance were presented to the Abbey by Pepin.

Echternach continued to have royal patronage from the house of Charlemagne. Though the monks were displaced by secular canons of the bishop of Trier, 859 - 971, and though Willibrord's buildings burned down in 1017, the Romanesque basilica with symmetrical towers still houses his tomb in its crypt. As the abbey, with a famous library and scriptorium flourished, the town of Echternach formed around the abbey's outer walls and was granted a city charter in 1236. The abbey was rebuilt in a handsome Baroque range in 1737. The monks were dispersed in 1797, and the abbey's contents and its famous library were auctioned off. Some of the library's early manuscripts are at the Bibliothèque Nationale, Paris. A porcelain factory was established in the abbey, and the town declined, until the railroad brought tourists.
