Kosciusko is an unincorporated community in Wilson County, Texas, United States.

[2][3] The settlement was named after Tadeusz Kościuszko, a military general of Polish origin, who served in the Continental Army during the American Revolution.

At this time, there were approximately four businesses located in Kosciusko, including a blacksmith, meat market, and garage.

In 1934, electricity arrived to the town of Kosciusko, allowing homes to be hooked-up for a cost of $5.

At this time Kosciusko had a population of 700 people, the vast majority of whom were located in the surrounding farms and ranches.

As farming became less profitable, many people began to leave the community in search of employment in the city of San Antonio and surrounding small towns.

The vast majority of Kosciusko's current inhabitants trace their lineage back to the original founding families.

Today the town consists of St. Ann's Catholic Church - a painted church, St. Ann's Cemetery, Kosciusko Hall - a dance hall,a gas station and fertilizer company, the local water supply corporation, a plumbing company, a concrete plant, as well as numerous farms and ranches.

Kosciusko remains an active community, known for its annual picnic - always celebrated the first weekend of August.

It had a beautiful hand carved wooden altar, and was built facing to the west, the opposite of the current church today.

In 1935, a new rectory was built on the south side of the church, where the southern breeze would provide better cooling.

In 1998, in preparation for the Centennial Celebration, the wooden stained glass doors were installed at the entrance of the church.

In 2007 the interior of the church was remodeled, and painted by Polish Artist Cezary Sienkiel.

In 1918 a convent was built for the Sisters of Charity of the Incarnate Word, and another room was added to the schoolhouse.

The team was composed of local men who played in the small town bluebonnet league.
