For a cool $52 million, you can have one of your own 5th Avenue mansions! 991 Fifth Avenue, one of the last mansions of its kind, recently hit the market. Now home to Irish American Historical Society, the building was originally commissioned by Mary Augusta King, daughter of former New York Governor John A. King. King hired architects James R. Turner and William. G. Killian to design the bowed front brick and limestone structure. It was completed in 1901.

Upon Mary’s death, just four short years after the mansion was complete, it was purchased by banker David Crawford Clark, according to the Daytonian in Manhattan. Clark hired Ogden Codman, Jr. to renovate the interior spaces. The American Irish Historical Society purchased the building for just  $145,000 in 1939 and has remained there ever since. When news of the sale broke in early 2021, there was an outcry in the Irish American community. Even the Irish government opposed the sale.
