Jefferson National Expansion Memorial
Things To Know Before You Come
The Old Courthouse with the Gateway Arch behind

The Gateway Arch, Old Courthouse and grounds of Jefferson National Expansion Memorial (JNEM) form a natural focal point for a vibrant downtown St. Louis. As an urban site, JNEM offers an oasis to visitors, while remaining in proximity to a number of local attractions, hotels, and restaurants.

Visitors will find a number of downtown hotspots easily within walking distance, including historic Laclede’s Landing, trendy Washington Avenue and the recently rebuilt Busch Stadium, not to mention the storied Mississippi River.

Visitors can expect a variety of weather typical in the Midwest, though the urban landscape creates some unique climatic variables. Summer temperatures typically exceed those of outlying areas due to the “heat island” effect. Winter winds form blustery eddies around tall buildings and gust through “street canyons” formed by passages between buildings. During spring and fall, the weather can change dramatically within a short period of time. Visitors can best prepare by dressing in layers that will protect them from wind and precipitation, and easily be removed in fair weather.

Due to security measures at the Gateway Arch all visitors to the Arch must pass through a security checkpoint. If you have pre-purchased your tram ticket, please arrive at least 30 minutes before your tram time.
