provide one park for each of the ten square miles under its jurisdiction. Beginning in 1914, the district began to purchase land for what would eventually become Mozart, Kelyvn, and Kosciuszko Parks, and improvement on these three sites began almost immediately. For Kosciuszko, noted architect Albert A. Schwartz designed a Tudor revival-style fieldhouse, expanded in 1936 to include an assembly hall, just two years after the 22 separate park districts were consolidated into the Chicago Park District. The park complex expanded during the 1980s with the addition of a new natatorium at the corner of Diversey and Avers. The green space afforded by the park quickly became the backdrop for community gatherings. Residents utilized the grounds at Kosciuszko Park for bonfires, festivals and neighborhood celebrations, and for a time, even an ice skating rink that would be set up every winter. Summertime brought the opportunity for outdoor festivities, peppered with sports and amateur shows featuring softball games, social dancing, a music appreciation hour, and the occasional visit by the city's "mobile zoo". Today "The Land of Koz" is a diverse neighborhood, and becoming even more so as gentrification advances further northwest. New people are entering Kosciuszko Park and joining earlier residents whose roots trace back to Latin America and Poland. Yet the park that lent the neighborhood its name still serves its residents, where through play, performance, and even the occasional outdoor film screening it functions as the venue where the community can come together.
