In beta 1.6.4 you can make a hatch
A portcullis is a heavy metal grate used as a gate. The guards raised the portcullis of the castle.
Portcullis House (PCH) is an office building in Westminster, London, UK. Portcullis House is a seven story building. The building was designed by Michael Hopkins and Partners.
When attackers attacked the castle, if a portcullis existed , it could come from above and kill them. I hope it helped :) ^^
