The first large community in this
section was about six miles from the present town and was called "Old Allendale" or "Buddenville".
This community had four stores, one academy (established in 1870 - which was the pride of the
countryside), and a Baptist Church with a Parsonage. During those days the mail was brought to
Buddenville by horseback from Barnwell.
As the neighborhood became more thickly settled, they applied for a post office. After securing the post office, it was necessary to secure a name for their village. Many names were discussed and finally the name "Allendale" was chosen. An act to charter the town of Allendale was passed by the State Legislature on December 20, 1873. The first town hall was located on the same lot where the present town hall stands. This was a small one-room frame structure with a piazza across the front. In 1901, the present town hall was built, and a town government was set-up.
In the middle 1940s, the much traveled North-South Federal Highway 301 brought a tourist trade that has always been of considerable value to the town's economics. Also, being on the fringe of the Savannah River Plant in recent years has brought many people from all over the country to live in Allendale. This influx has added to the community and has brought additional enrollment to our schools, churches, and business community.
