Romulan Senate chamber The Romulan Senate chamber was a large , circular room located in the center of a concentric seaside city on Romulus . It was within this grandiose building that the Senate of the Romulan Star Empire convened . Within the chamber , there was a large statue of the imperial symbol over the main entrance to the room . The symbol was that of a bird - of - prey holding the two planet s of the Romulan system , Romulus and Remus . The main body of the Senate sat in three rows near the entrance of the room . The Praetor and the Continuing Committee sat on the other side of the chamber . As of 2379 , The floor in the center of the room had a map of the Empire that also showed the Neutral Zone ; this area was used for anyone wishing to address the Senate . On the wall opposite the main entrance was a large display screen where the Senate could review information or communicate with anyone outside the Senate chamber . In 2154 , the Senate chamber could be seen in the background behind the building Senator Valdore was controlling his drone ships from . ( ) In 2379 , this chamber was the site of the assassination of the entire Romulan Senate with the exception of Senator Tal ' aura , who planted a miniature thalaron radiation projector that killed her fellow senators . The first Federation citizen to have ever set foot in the chamber was Captain Jean - Luc Picard in 2379 , when he was invited there by Praetor Shinzon after he seized power upon orchestrating the assassination of the Senate . ( ) Appendices . Background information . A miniature of the Romulan Senate chamber was created by Rob Woodruff and helped Conceptual Artist Tom Southwell to storyboard the scenes which were set in that room . ( " Storyboarding the Action " , " Star Trek Nemesis ( Special Edition ) " DVD ) The sets for the interiors of the Romulan Senate chamber were constructed on Paramount Stage 32 . ( " Star Trek Nemesis " call sheets ) In a line from the episode that was in the " Final Draft " script but not the aired episode , Benjamin Sisko tells Vreenak that proof of a Dominion attack on the Empire would mean nothing if the Romulans waited " " until there were Jem ' Hadar soldiers standing in your Senate chamber before you decided that the Founder s weren ' t your friends after all . " " Location . In the for , the establishing matte painting ( which was later re - used for ) was described as an exterior view of the " Capitol city " of Romulus in daylight , which the Krocton Segment might have been implied to be a part of . Although they are both concentric , it is markedly different than the city around the Senate chamber shown in both " Nemesis " as well as in " Babel One " / " United " / " The Aenar " ( both installments use the exact same CGI model ) . As " Nemesis " and " Star Trek : Enterprise " take place after and before " Unification " , respectively , the different appearances of the " Capitol city " on the one hand and the city surrounding the Senate chamber on the other hand are difficult to explain with a simple change of the city - scape over time . It is , however , possible both shots ( Nemesis / Enterprise vs . TNG / DS9 ) show different parts of the same city , which might contain more than one such concentric area , therefore retaining the " Capitol city " as the location of the Senate chamber . Apocrypha . In many of the " Star Trek " novels , including " Vulcan ' s Heart " , " " : " Taking Wing " , ' : " The Good That Men Do " , " Enterprise " : ' , " " : " Rogue " , and the " Vulcan ' s Soul " trilogy , the Romulan capitol building is referred to as the " Hall of State " .
