Travelers, the insurance company, is launching a $30 million maintenance investment to renovate the exterior of its iconic Travelers Tower in Hartford. The company has owned the tower and adjoining office building since it construction in 1919.

The project will repair, upgrade and replace exterior building elements on the 527-foot (161-meter) tall tower, Travelers' spokesman Jennifer Wislocki told local media.

The repairs will include corrections to minor cracks in the granite surface of the building, repairs to mortar joints and surface corrosion, and the replacement of the building's windows, drainage systems and some cast iron elements, the Hartford Courant reports.

The tower was designed by architect Donn Barber, who also designed the Connecticut State Library and Supreme Court Building. When it first opened, the tower was reportedly the seventh tallest building in the world.

Traveler's Tower is currently the second tallest building in Hartford, eight feet shorter than City Place. Find a list of Hartford's tallest buildings here.
