Peder Fredags Gränd is a small blind alley in Gamla stan, the old town in central Stockholm, Sweden.
The inconspicuous alley remained nameless until the 20th century; it is included on a map from 1700, but completely left out on another dated 1733.
[1] Peder Fredag (–1525) was probably one of the burghers of Stockholm, who first appeared in historical records in 1520 when, confronted with Christian II of Denmark, he vehemently opposed the city's terms of surrender.
Before the Danes marched into the city, he escaped to the north of Sweden where he began to amass people to revolt against the Danish king.
He started to raid the Stockholm Archipelago with his yacht, and in 1521 he joined the party of Gustav Vasa who eventually gave him a letter of marque.
