A monument usable for locating stationary geographical positions and/or assets includes a housing, comprising a body and a cap; at least one permanent magnet mounted on or in the housing; and at least one electronic marker located on or in the housing. The magnet has a magnetic field of sufficient strength for its location to be readily identified from outside the housing using a portable magnetic locator and the electronic marker includes an electronic transceiver for receiving and/or transmitting electronic information unique to the geographical location and/or functional properties of the monument or an asset associated with the monument.
