In the 1860s the Society of Animal and Plant Acclimatization attempted to resume 17th century experiments and set up a model honey bee and silk worm farms on the site of the historical proso farm. Exhibition hall of the Society, built in the 1880s by an unnamed English engineer, was the first reinforced concrete building in Moscow. Existing trees of the regular Izmaylovo Park were planted in the same period (1865–1890).Pamyatniki, p.68
