The former Pest city wall was standing here up the the end of the 18th century. Roughly 5 second hand shops, and used book shops can be found here. Jeans for 3-4€, baby clothes 1-2€, old postcards, and really great old maps are available here to. Karoly korut is just outside the Dohany Temple which is the gate to the beautiful and compact little neighborhood, called the Jewish Quarter. Highly recommended!
