Next to the Palace of Agriculture, of which it is the southern extension, stands the Palace of Horticulture. As the crow flies, it looks like a rectangle cut in the middle by a square, which gives it the shape of a Greek cross. It is one of the few buildings at the Exhibition that has more than four sides.
It measures 270 metres in front and 150 metres in depth, and occupies the highest site of the Exhibition, which it dominates with its parterres.
It is surrounded by beautiful gardens and flowerbeds, shrubs with various types of foliage and lawns.
The architecture is based on the same principles as that of the Palais de l'Agriculture; the same projecting pylons resting on a plain base.
The main entrance is square. Cut by a horizontal lintel, it has a projecting cornice that joins the two openwork belfries that rise from the sides and distinguish the building from its neighbour.
The entire façade of the central square is higher and decorated with some sculptures. A balustrade, enhanced at regular intervals with flags, runs around the cornice.
The lower sides are in the same style. The roofs are flat and glazed, cut into two pieces; the upper bays are arched over metal supports and form a frame over the second part which itself ends in a canopy. The large side doors are square and finished with a triangular pediment without ornamentation.
The interior offers the seductions of elegance and comfort; it consists of a square room, with wings on all four sides, an arrangement indicated by the plan of the building. All the exhibitors are on the ground floor. In the middle of the inner courtyard, under the open sky, a decor of palm trees, green plants and tall tropical flowers adds a bright and fresh note.
Ventilation and lighting are perfect. The light comes from the windows on the facades and from the monitors on the roofs, and in such a way that the sun cannot touch the exhibits or bother the visitors.
A restaurant, a tea garden, a reading and correspondence room make it a very busy place.
The exhibition is not without its own interest. It is the most complete of its kind that we have seen so far. It should have included, but did not include, everything that concerns Horticulture: ornamental plants and vegetable plants, carrots and roses, the useful and the pleasant; apparatus and methods of pomology, viticulture, floriculture, arboriculture, the tools of the gardener and the nurseryman; desserres, aquariums, garden designs, plans, models, tables and technical books. Only pomology was brilliantly represented by the whole variety of fruits of California.
A wing was reserved for beekeeping, where all varieties of bees could be seen at their daily task.
