I visited Leipzig (Germany) on 30 September (2015)—1 October (2015) at the occasion of this year's BuildMoNa colloquium (on unconventional superconductivity).
I had little time to visit the city itself but as the center is very small, I could quickly wander between the two main churches, passing by Faust's Mädlerpassage [1] and feel the eerie sensation of finding myself, at last, in the church where Bach performed the Matthäuspassion.
