Stonehenge and Big Ben

Hello.
 
These last few weeks I have been researching famous british landmarks, inparticular Stonehenge and Big Ben. From my research I have found that stonehenge was built between 3000BC and 1600BC, and took more than 30 million hours to build.                                                                             
 
Below is a picture of Stonhenge:

I have also been researching Big Ben. From this research I have found where the clock is situated and more about the structure. one of the most interesting things I found was that each of the dials on the clock contains 312 pieces of pot opal glass, which is a type of glass that is opaque.

I will carry on researching famous landmarks including the Houses Of Parliament and Buckingham Palace.
