The Administration Building, which is temporarily closed for renovation, normally houses the Registrar’s Office, the College of Engineering Dean’s Office, and the College of Sciences Dean’s Office. (Photo by Nicole Cappello)

The first level of the Tower is a windowless room above the fourth floor of the Administration Building.

A wooden ladder provides access to the Tower’s second floor.

The second level of the Tower, with windows on three sides, is a holding area for replacement parts for the Tower’s neon letters.

The letters T-E-C-H have been outlined in neon since the 1950s.

A mousetrap is chained to the floor.

The third (and top) floor of the Tower has windows on all four sides.

Some nooks and crannies bear the names of ANAK Society members. These students sign their names in the Tower during their senior year.

The cobwebs on this Technique tacked to a Tower beam perfectly complement this Friday the 13th edition.

A ladder attached to the wall leads to the top of the inside of the Tower’s finial.

The Tower’s security system includes cameras.

Tower windows offer outstanding vistas of Atlanta, including a view of the AT&T Building and the Bank of America Plaza — with Bobby Dodd Stadium in the foreground.

Even from inside the T-E-C-H, there are panoramic views of the city.

The height from the ground floor (Highland Bakery level) to the top of Tech Tower is 145 feet.

On a clear day, you can see for miles.
