I love the musical stamp and the clever shot of the postcard!
Halle an der Saale is a city in the German state of Saxony-Anhalt. Halle is a very important economy and education-center in east Germany. The University of Halle-Wittenberg is the biggest university in Saxony-Anhalt and one of the oldest Universities in Germany.
The city is situated in the southern part of Saxony-Anhalt, along the river Saale which drains the surrounding plains and the greater part of the neighbouring Free State of Thuringia located just to its south, and the Thuringian basin, northwards from the Thuringian Forest. Leipzig, one of the other major cities of eastern Germany, is only 35 km away.
Halle's early history is connected with harvesting of salt. The name Halle reflects early Celtic settlement given that 'halen' is the Brythonic (Welsh/Breton) word for salt. The name of the river Saale also contains the Germanic root for salt, and salt-harvesting has taken place in Halle at least since the Bronze Age (2300-600 BC).
Sandra mentions in the card that Halle's nickname is "City of five towers" and you can appreciate it on the card actually, four of the towers are from the main church and the other is the "Red Tower" located right next to the church.
