Maftehot Haor - The Keys of Light - This is the work of the Dutch artist Mr. Beam. Pianists: Yoel Shemesh and Roi Lauterbach. At the heart of this installation is the idea that, in fact, the piano keys are only white and black, but they sound like millions of different colors and shades. Each visitor can touch the keys and see how the sound develops into the light. Each key creates a different glow, and any melody turns into a symphony of light.
The blue route starts on Tsakhal Square (opposite the city hall), runs along the walls of the Old City and ends at the entrance to the Western Wall. This is the longest route. At the end of the route there is a stop of special buses, which, having rounded the old city, will take you back to the starting point and you can go on another route: either green or red. Green goes along the northern walls of the Old City, and the red passes through the city from the Jaffa Gate to the New Gate. The festival takes place every day from June 26 to July 4 from 8:00 pm to 11:00 pm, except for Fridays.
