Atlantis control tower

The control tower in Atlantis is the central building of the Ancient city-ship and is said to be approximately 70 floors tall. The central tower of Atlantis contains some of the most vital areas in the city, including the Gate room and the jumper bay, and a balcony outside the Gate room provides a great view of the city and surrounding landscape. Because the Stargate is housed in it the control tower is better armoured than the other areas of the city, and the city is programmed to prioritize the areas closer to the tower if the city and its inhabitants would be threatened in some way or if power was failing. Other important locations include the Commander's office, the conference room where the Lantean Council once met, the infirmary, and the holo room. During their first year, the Atlantis Expedition stayed within the area immediately surrounding the tower, but they have since expanded to other areas of the city. The control tower is also the place of Michael Kenmore's death.

The levels of the tower are as such:


 * Jumper bay

It is also apparent that Lt. Col. Sheppard's quarters are in the tower

Trivia
The Control tower has a striking resemblance to the tower showed in the BBC Sci-Fi series Doctor Who in the episode Dalek.

The stairs in the control tower say:

01 WE HOLD THESE AS THE TRUTH 02 A HEARTY WELCOME TO THOSE OF OTHER WORLDS 03 VISITING OUR HOME FOR THE FIRST TIME (W)ELCOME AGAIN 05 TO THOSE RETURNING YOU Y HAVE BEEN GONE TOO LONG AND YOUR 04 ABSENCE HAS WEIGHED HEAVILY ON OUR SOULS WE ARE 07 WHOLE AGAIN THAT YOU ARE AMONG US AND WE CELEBRATE YOU BEING HERE AGAIN 06 AS WE LEAVE FOR DISTANT WORLDS WE PLEDGE TO RESPECT THE LANDS OF 08 OUR NEIGHBOURS AND TO ACT WITH INTEGRITY AS AMBASSADORS IN PEACE TIME 09 OF OUR PEOPLE TRAVELLERS WITH OPEN HEARTS WILL ALWAYS BE WELCOME REFUGEES 11 FROM TYRANNY MAY SEEK SHELTER UNDER OUR ROOF AND KNAT OUR PEOPLE WILL LAY 12 DOWN THEIR LIVES TO PROTECT THE WEAK AND THE JUST LET THIS BE OUR LEDGE TO THOSE 10 INHABITANTS OF THIS WORLD AND ALL WE MAY EVER KNOW WE WILL ALWAYS STRIVE TO 13 COME IN PEACE AS WE GO IN PEACE AND YOU WILL BE WELCOME ON OUR SHORES FOREVERMORE

The numbers correspond to the stair, but they had to be rearranged a little to make sense.
