Russian Neurosurgical Research Institute situated at 12 Mayakovskogo Street. It was founded as the Leningrad Practice Institute for Surgical Neuropathology in the former Alexandrinskaya Women's Hospital in 1926, replacing the Neurosurgical Institute established by L. M. Pussep as a part of the Psychoneurological Institute in 1918, which was closed in 1922. It was transformed into a research institute in 1938. The institute has a Russian Epilepsy Centre and is a clinical base for neurological and neurosurgical departments of St. Petersburg's medical institutions. Among members of the institute were V. G. Molotkov, the founder and first director, A. L. Polenov whose name was given to the institute in 1947 with a bronze bust installed in front of the building, as well as I. S. Babchin and V. N. Shamov, memorial plaques attached to the building in their honour. The building itself was erected in the memory of a daughter of the Emperor Nicholas II. A marble memorial plaque and a bust of Grand Duchess Alexandra Nikolaevna by sculptor I. P. Vitali, which used to stand by the entrance of the hospital church, were not retained. The building was reconstructed in 1937-39.
