It has a glass factory and is known as glass-maker village. The first time glass was made in Piesau was in 1622. Up until today glass is the main reason of existence in Piesau. Carl Heinz Glass still produces glass, for instance for the cosmetics industry. The inventor of the first usable röntgenglass (Carl Heinrich Florenz Müller) descends from the village. Piesau lies next to the "Rennsteig", a hiking path of more than 160 kilometres throughout Thüringen.
