Category pages
Hello, I noticed you are attempting to add items directly to a category. You have been editing the page Category:Road tunnels in Greece. Note the first word in the title of the page you've been editing is "Category". That's because it is a category. It's not an article, and it is not intended to be an exhaustive list of all items that fit the description. A category page is merely a collection of related and existing Wikipedia articles or pages.

In Wikipedia, we do not add pages to a category by editing the category page, we add them by linking to the category from the individual articles' pages.

Please see Help:Category and note the section Help:Category.

And please read FAQ/Categorization as it states what I'm saying in a nutshell.

Add the category to the articles, not the other way around.

It seems the content you are wanting to add would better suited for a page titled List of road tunnels in Greece. Unfortunately no such list-type article exists for that topic. To create that page you would have to submit a request at Articles for creation.

Thank you and have a great day! --DB1729 (talk) 15:29, 11 February 2021 (UTC)
