English: BT 4x4 ("Beobachtungsturm 4x4") is a type of command post / watchtower built for the East German borderguards at the Inner German border or at the wall around West-Berlin. The square shape with dimensions of 4 by 4 metres is characteristic for this tower type, as the other common square border tower type (BT-9) is more slender with dimensions of 2 x 2 metres. The other visual key difference between the two types are the windows on the top floor: The windows of the BT 4x4 do not run the full width of the tower whereas the windows in the BT-9 do.

Other common abbreviations for the BT 4x4 are BTv 4x4 ("Beobachtungsturm viereckig, 4x4") or FüSt ("Führungsstelle"). The tower has the following levels:

  • Basement
  • Ground floor with arrest cells
  • 1st floor with sleeping compartments for a half squad, with two small windows per side, suitable as a loophole
  • 2nd floor with observation platform, and alarm and signalling equipment. Four windows face each of the four sides.
  • Roof, with railing and search light, possibly antennas
