Flood Tunnel

Flood tunnel, Utrecht, The Netherlands. Underground flood tunnel in the city Utrecht, The Netherlands. This 120 meter (400 ft) long concrete underground tunnel in the center of the city is not accessible for public. During a transitioning phase of re-opening part of the formerly closed canals in the city we had the chance of getting into this tunnel and sampling it for your pleasure. This place is concrete all over, great for choirs, low frequency synth drones, new age pads or sound effects.
