The National City Historical society works diligently and tirelessly to preserve our historic sites. We have five national sites Brick Row built in 1887 to house the railroad executives who came from the east coast. Brick Row is a replica ten unit Philadelphia row houses that extends along the entire 900 block of A Avenue. The other four sites are Granger Music Hall at 1615 E 4th Street in National City currently on the endangered list built in the late 1880s and was designed by famous architect Irving Gill. It was his first attempt at Japanese motif and shake shingles. Granger Music Hall is a beauty and we are in serious need of help toward its preservation. The hall was built with perfect acoustics for chamber music. The City of National City is working toward relocating the hall restoring the building and showcasing it through the National City Historical Society as a main venue. The last event was held in 2009. There is St Matthews Church a Victorian Steeple Church also built in the 1880s and it is located at 521 E 8th street in National City. It is privately owned and is a full functioning renovated church.

There is the Historic Train Depot located at 823w23rd Street and it is open for viewing on the weekends.   It is currently run by the San Diego Electric Railroad.
