Local.emacs?

Question

emacs

In vim, in addition to the main .vimrc, you can (for example, in the root of the project) put a file that will only work for the current folder (and its subdirectories).
Is it possible to do the same in Emacs?
(Well, or using projectile somehow, but in the root of the project)
