SW to Create a Web Site

[Piper]

Does anybody know of SW which is compatible with Ubuntu and can be used to 
set up a WWW site on your own PC?

I was using Geocities but they are shutting down later this year so this 
thought came to mind: maybe you can carry this same kind of information on a 
Linux machine. I have used the Geocities WWW's only for text and scanned in 
pictures, nothing too fancy.
