Tykocin

Not very far outside Bialystok (I believe there's a bus) lies the town of Tykocin, best known for the still-operating Jewish synagogue and the site of a significant Nazi pogrom against Polish Jews. (Wikipedia entry for the Tykocin pogrom ). I have seen the synagogue -- which is reportedly operated by groups of Israeli Jews who make something of a pilgrimage here several times a year to keep it open and to run an associated museum.
