Designed by Vilhelm Dahlerup, the Dipylon structure was built in 1892, at a time when the Ny Carlsberg complex was still under redevelopment and far from finished.

The gateway of the lower part marked the Vesterbro-side entrance to the Ny Carlsberg complex, complementing the Elephant Gate to the west which afforded access to the brewery from the Valby side.

[1] The Dipylon building is built in red brick in the ornate Historicist style which is typical both of the Carlsberg area in general and especially of Vilhelm Dahlerup's work.

Similarly placed on the rear (courtyard) side of the structure, there is a plate which is inscribed with a quotation from J.C. Jacobsen's will which was later adopted by Carl Jacobsen as a motto:[3] In the brewery's operations, a constant goal, regardless of immediate gain, should be to develop the art of making beer to the greatest possible degree of perfection so that the brewery and its products may ever serve as a model and, by their example, assist in keeping beer brewing in this country at a high and honourable level.On the rear side of the gate building, a frieze consisting of nine tile paintings depicts various key figures in the construction and operation of brewery.

In the centre stands Carl Jacobsen, flanked by his wife, Ottilia, and his son Alf who was the chosen heir but died in 1890 shortly before the building was completed.
