St. Adalbert's Fair (Jarmark św. Wojciecha) has been held for more than twenty years at the turn of April and May at the Rev. Krzysztof Kluk Museum of Agriculture in Ciechanowiec. It refers back to the 19th-century fairs that lasted up to two weeks here, trading mainly in horses, but also cattle, sheep, grain and small goods.
Today folk artists, artists and craftspeople from different parts of Poland come here. There are craft demonstrations, stalls with local and regional dishes, honey, ornamental plants and tree and shrub seedlings, as well as artistic performances.
