Synergy

Finally, I understood what this word means :-)
After writing about beer, the next day was sunny and by joining a city named Plzeň which is two hours far by train from Prague.

There is also the central square (Náměstí Republiky) with St. Bartholomew church in it.

After climbing up its 100m tower I could enjoy looking at the city

And find the Brewery museum

In order to taste the local product :-)
