You must write up an entry for your assigned site. Think about a good tour guide book and what includes: basic facts and dates, historical importance, unique –perhaps even comical-insights, architectural details, and so on. Remember that tourists are in a hurry, so be sure to balance the need for important information with brevity. Still, your description must be based on facts, so use citations similar to those found in any history paper (although for new sites and businesses you may have to use verifiable websites).
I will give you the assigned site when you got the job.
