310 West Church Street Apartments, Historic apartment building in Downtown Jacksonville, United States

310 West Church Street Apartments is a six-story brick building in downtown Jacksonville with an H-shaped floor plan. The layout ensures natural light reaches most residential units and places many apartments in corner positions.

Designed by Hentz, Reid and Adler, the six-story brick building opened in 1924 as upscale apartments. It became a hotel in 1944, operating as the Three-Ten, Southland, Griner and finally Ambassador Hotel from 1955. Added to the National Register of Historic Places in 1983, it closed in 1998 and is being renovated as the Hotel Merrydelle.

The building's successive hotel names mark its history: Three-Ten Hotel in 1944, Hotel Southland in 1947, Griner Hotel in 1949 and Ambassador Hotel in 1955. The name Ambassador stayed with the property through its later decline and closure in 1998.

The entrance features large rusticated ashlar stonework with decorative scroll keystone details that are easy to spot when visiting. The downtown location makes it simple to view the building from multiple angles and approach it from different streets.

The building achieves the unusual feature of having most units placed in corner positions, a rare arrangement in residential design. This happened because the H-shaped floor plan created multiple corner locations that allow for extra windows and views.
