There are two dates engraved on the town hall’s portico – 1927, the year Box Hill was proclaimed a city, and 1994, the year of amalgamation. The crest of the former City of Box Hill is also featured on the portico.
The inscription on the town hall's portico commemorates the history of Box Hill, highlighting its transition from a separate municipality to a part of a larger entity through amalgamation in 1994. The crest of the former City of Box Hill serves as a visual reminder of this past identity.
