For most sci-fi movies/tv series ship bridge/main control room is exposed (external part of ship). Examples:

* *Star Wars* Star Destroyers
* *Stargate* Dedalus/Destiny/Atlantis(top of main highest tower)
* *Star Trek* Enterprise
* *Prometheus* USCSS Prometheus
* ...

Why such crucial place is exposed so even small enemy ship can destroy all control equipment/kill officers? Is not better to hide bridge like in *Battlestar Galactica* deep inside central part of ship with thick hull and observe everything using sensors?

I know that for beautiful views and drama it has to be done like this so even very weak opponent could take down "Goliath" but I wonder if there are any other advantages of locating command center in external part of ships.
