Hezakiah`s Aquaduct

A tunnel was constructed from the spring at Gihon - what is now called the Virgin`s Fountain - under the city walls and through the rock to the southern end of the city of Jerusalem, to the pool of Siloam. This would be a difficult feat in these days of sophisticated surveying and measuring equipment. It was even more remarkable for the times of Hezekiah, because the impending invasion meant there was very little time and gangs of workmen had to start from either end. When the tunnel was complete, the spring outside the city was blocked up and the water flowed into the city. [Archaeology]
