Abstract. A collection of n hyperplanes in
${Bbb R}$ d forms a hyperplane arrangement. The depth of a point
$ heta in {Bbb R}^d$ is the smallest number of hyperplanes crossed by any ray emanating from θ . For d=2 we prove that there always exists a point θ with depth at least
$lceil n/3
ceil$ . For higher dimensions we conjecture that the maximal depth is at least
$lceil n/(d+1)
ceil$ . For arrangements in general position, an upper bound on the maximal depth is also established. Finally, we discuss algorithms to compute points with maximal depth.
