Wrocław ma swój południk. Jest to "szczęśliwy południk", jak mawia były prezydent Rafał Dutkiewicz - z wykształcenia matematyk. Miasto przecina bowiem 17. południk długości geograficznej wschodniej. Do 2008 roku nie było to jednak nigdzie wyraźnie zaznaczone.

Wiele źródeł błędnie podaje, że 17. południk przechodzi przez Wieżę Matematyczną Uniwersytetu Wrocławskiego, myląc go z wybudowaną tu linią południkową. W rzeczywistości 17. południk biegnie od niej 2 minuty i 5 sekund kątowych na zachód, przecinając m.in. Most Milenijny. W tym właśnie miejscu w 2004 roku ustawiono marker lokalnego południka - granitową płytę z napisem "17 południk", a na linii południka umieszczono na moście okolicznościowy drogowskaz.
