In this small square on Carrer de la Força you can study a tar-blackened 3-inch-long, half-inch-deep groove carved shoulder-high into the stone of the right-hand door post as you enter the square. It indicates the location of a mezuzah, a small case or tube of metal or wood containing a piece of parchment with verses from the Torah (declaring the essence of Jewish belief in one God). Anyone passing through the doorway touched the mezuzah as a sign of devotion. Evidence
of the labyrinthine layout of a few street ruts in the Old Quarter may still be seen inside the antiques store Antiguitats la Canonja Vella at Carrer de la Força 33.
