It was built about 5000 yrars ago so nobody knows.
To build the whole of Stonehenge will obviously depend on how many people there was for the task. What we suggested was that, given a great concentration of effort, is the sarsen structures, the biggest bits of Stonehenge, could have been built within a period of three years. We suspect that probably it took longer. There is the opinion that Stonehenge was constructed in sections over a period of time that span as many as 300 to 500 years.
it takes 79 people to build a normal sized hose

The number is uncounted, so no one knows.
