Hi! first of all you're writing an essay basically about the Lincoln Memorial. Since you need an introductory paragraph, write that down first. Secondly, you need to write your thesis statement at the end of your introductory paragraph. So let's look at an example before I give you your thesis statement. This one will be about Abraham Lincoln.
Abraham Lincoln was an influential president.
Sounds kinda boring doesn't it? Well, to make a strong thesis statement, change the words a little bit.
Abraham Lincoln's Emancipation Proclamation was the most influential part of his presidency.
Now THAT sounds better doesn't it?
So... your thesis statement for the Lincoln memorial would be something like this:
The Lincoln Memorial was one of the most influential buildings in the world.
Something like that.
Hope this helps!
