Tajbeg Palace or Tapa-e-Tajbeg is a palace built in the 1920s and located about 10 miles (16 km) outside the centre of Kabul, Afghanistan. The stately mansion sits atop a knoll among foothills where the Afghan royal family once hunted and picnicked. It should not be confused with Darul Aman Palace, which is about 1.3km northeast from Tajbeg.
Built to house the Afghan royal family, Tajbeg Palace is one of the most impressive landmarks of "Darulaman," newly created during the era of Amānullāh Khān by a team of European architects in an attempt to establish a new seat of government and modernise Afghanistan, both of which ultimately failed when religious conservatives forced Amānullāh from power and halted his reforms, leaving the palace in ruins as it has been for much of its existence.
