I know! To make it different than all of the others, make it so that the dwarves worship some OTHER kind of god for a change!
Like...a forest god, who demands offerings of your finest wooden crafts and elves to tend the shrine!
Or...a fishing god, who needs a temple built in water (like, an area of dry constructions surrounded by water on all sides), with piers for fishing upstairs.
Or...a wind god, who needs a shrine built high above the ground, with long, thin platforms without railings connecting bigger platforms that serve as rooms.
Or anything else non-cliche, really.
Maybe the whole fortress could be built on that religious theme.
