Even on these hot, hot summer days, this city is cool: the streets are lined with nettletrees. They keep a wonderful microclimate.
Also on the street, where the synagogue is located.
The synagogue is in pretty good state. It is not to be visited, but on special occasions.
Location of Synagogues
As on this city plan of Vác can be seen, the synagogue is located a little bit outside the old town. Often behind the city gate, in former suburbs, where is the 1850s the city developed floorished. so, if you look for the remains of synagogue look there: on the other side of the former city wall, behind the city gate or the former moat. Where houses are from the architectural period of historism. That is the place to look for a synagogue.
