Going Underground

Tunnel, Madrid, Spain

This road and tunnel are located near the site where the Inquisition began in Spain.  

While likely unintentional, the arrow in the street can be seen as a metaphor for the Jewish Conversos (aka Marranos) who remained in Spain after 1492.  To remain in Spain, these Jews assumed Christian identities, but did their best to remain Jewish secretly.

The Spanish Inquisition lasted over 350 years (from 1478 to 1834) and it wasn't until 1968 that the decree expelling Jews was rescinded.
