The House of P. A. Vyazemsky, also known as the Vyazemsky estate, is located in Moscow at Voznesensky Lane, building 9, structure 4. This house belonged to Prince P. A. Vyazemsky, a renowned writer and friend of Pushkin.

The building was erected in the 1820s. In 1824, A. S. Griboedov presented his work "Woe from Wit" here. A. S. Pushkin also visited this house, where in 1826 he read his tragedy "Boris Godunov." In 1830, after arriving from St. Petersburg, Pushkin stayed with Vyazemsky from August to September, after which he left for Boldino in early September. A plaque on the facade of the house commemorates these events.

In 1845, before moving to St. Petersburg after receiving an appointment, P. A. Vyazemsky sold this house.
