The Round Top Vintage Market is held twice a year in the spring and fall. I must admit that the scheduling of the show has always confused me. I finally figured out that there isn't one group in charge of the Round Top Antiques Market. It is actually multiple independent events, and each one has its own vendors. Also, Round Top isn't located just in Round Top. It is also in Warrenton and Carmine. You can find the dates here.
