About CNB Bank & Trust

Trust in a bank is built over time—not just over months or years, but through decades, and in some cases, centuries. Our history dates back to 1854 with the founding of a bank in Carrollton, IL, recognized as the oldest continuously active bank headquartered in Illinois (Source: FDIC Institution Directory).

Before July 2011, CNB Bank & Trust, N.A. operated as four individual sister banks under the Carlinville National Bank Shares, Inc. holding company: Carlinville National Bank, Citizens State Bank, Palmer Bank, and Cornerstone Bank & Trust, N.A. Over the years, these institutions came together, combining their strength and shared commitment to exceptional service, forming the trusted financial institution we are today.
