Building A Five Star Militaria Show

The third annual Greater New Orleans Militaria Show will be a 200 plus table event featuring military antiques, collectibles, vintage weapons and museum displays from numerous time periods and nations. The show will be located at the beautiful Castine Center in Mandeville, Louisiana on October 7th & 8th of 2023. Hosted by Old Patriot Militaria and Heartland Militaria Shows, our second event will be even larger than our first and will feature some of the most trusted and well respected names in the world of military antiques. Our focus is to build on the huge success of our first show and continue to establish it as a five-star militaria show. Our goal for the 2023 Greater New Orleans Militaria Show is to not only feature world class military antiques available to all who attend, but for it to also be a full capacity military history event that draws both national and international attention.

Moving Our Hobby Forward

The Greater New Orleans Militaria Show, our dealers and our partners are dedicated to the education, preservation and heartfelt appreciation of military history. We accomplish our goal by encouraging and actively promoting the display, exhibition, conservation and collecting of historic military artifacts. Many of our dealers and partners are some of the most trusted and recognized names in the world of military antiques. This unquestionable knowledge and passion for our hobby has led not only to a number of us having published our own works in the past, but many of us continue to be featured in a number of periodicals, books and television shows.


Old Patriot & Heartland invite all of you to our Second Annual Greater New Orleans Militaria Show. We are veteran owned, family companies that strive to provide the absolute best militaria show experience to both our dealers and the visiting public. We have a combined total of over thirty years of experience in buying and selling militaria. Matt has been hosting his successful Heartland Militaria & Bad Shot Gun Shows for many years and is now partnering with Old Patriot Militaria to bring a show like no other to the bayou country!
