The Stonehenge World Heritage Site is big – so big, it is actually split in two, with much of it around Avebury.
People have lived and worked in the area long before they were ever declared a World Heritage Site – so when someone needs to build something, how do you make sure it will not negatively affect the much loved sites?
That is where a new draft document of more than 150 A4 pages comes in.
Officially labelled a "supplementary planning document", Wiltshire Council's cabinet member for environment, Paul Sample JP, called it an "important draft document that will help protect an historic and vital part of our heritage".
It would act as guidance to people wanting to undertake any development – whether a small garden extension or a solar farm – and those making the final decisions.
However, as it is only a draft at the moment, Wiltshire Council has it open for consultation and wants to hear from the public.
Mr Sample JP said: "At Stonehenge and Avebury we have inherited one of the most important landscapes in the world.
"It's essential that there is clear guidance so that any planning decisions affecting the World Heritage Site do not impact it adversely."
It explains what needs to be taken into account and shows if there are extra assessments that need to be done to make sure a project will not impact the area negatively.
There are some considerations that you would not usually expect to find in a planning document.
For example, it discusses astronomy. That is because not only Stonehenge, but a few of the monuments – including Woodhenge and Durrington Walls – are shown to have alignments to solstices and lunar movements.
"We know Stonehenge was used as a kind of sun calendar," explained Melanie Pomeroy-Kellinger, who is a manager for archaeology, landscape and historic environment at Wiltshire Council.
"We can't allow a massive development on the line of midsummer solstice for example. That would interfere with people's enjoyment and understanding of the importance of those alignments."
Any development that is too tall for example, might affect the view, give off too much light pollution or reflections that could affect the sites.
It also talks about views in the area and how monuments connect to each other, some very obviously, like avenues and ridges.
"It's really important to think about it as ceremonial landscape," said Claire Selman, also a member of the team working with the council.
"They might have been designed to be visible from one another" she added, mentioning that many also have connections to rivers.
Trees and woodland are also mentioned – some in a positive light, but it also notes the fact that some already in the area do not fit, with one in particular affecting the winter solstice.
