Queen's Tower (Greek: Πύργος Βασιλίσσης, Pyrgos Vasilissis) is a former royal estate near Athens, Greece.
He built there a small neogothic castle for his wife, Queen Amalia.
After the abdication of King Otto, the estate was sold to the Serpieri family, who still own it.
The wines bottled on the estate are called "Tour la Reine" (French for Queen's Tower).
A nearby station of the Proastiakos suburban railway opened in 2014, Pyrgos Vasilissis, is named after the estate.
