309 Center Ave.

          The structure was built between 1858 – 1865 and was enlarged and received its Queen Anne affinities by John Cosgrove in 1879-1910.  By 1910 it appeared as it does today with the exception of a family room addition in 1966.  It features a projecting rectangular two-story bay on the west with a gable roof.  At the southwest is another rectangular bay which is set at an angle.  The primary entrance is a double leaf with a transom wherein is etched the name “John Cosgrove”.  A circular tower with a conical roof sits at the southeast corner.  Extending to the east is the one-story gabled addition.  It has vertical siding, sits on a concrete foundation, and has an east end chimney and a south entrance.  The basement under the front section was transformed into a living/bedroom area.  Furnished almost entirely in antiques, the interior has been extensively renovated in 1957 and 1966.  An alley to the east gives access to a two-car brick garage.  Between 1879 and 1925, John Cosgrove, US Senator, and prominent area attorney resided in the house.  Cosgrove was also active in civic projects and was instrumental in the securing of the tool-free road bridge across the Missouri River in 1924.
