The Ahinski Manor[1] (Belarusian: Сядзіба Агінскіх у Залесьсі) is an early-nineteenth-century country house located in the village of Zaliessie (also Zalesse), Smarhon district in Belarus.

[2] Michał Kleofas Ogiński, who had been in exile since the defeat of the Kościuszko uprising, returned to the Russian Empire in 1802, following an amnesty by the Tzar.

He settled in the Zaliessie estate and began construction of a new stone manor house in a classicist style by architect Michał Szulc [be].

In Zaliessie, Michał Kleofas Ogiński created many of his works, including the famous polonaise in A minor "Farewell to the Fatherland [be-tarask]”.

At the beginning of the twenty-first century the manor was in a poor state; however, between 2011 and 2015, large scale restoration works were undertaken.
