The aim of this paper is to discuss Roman coastal landscapes and sea-level forcing near Forum Julii (Fre ´jus, France). These new data demonstrate that the shoreline was a rocky coast with a biological mean sea level at À33 cm AE 6 cm N.G.F. This shoreline was buried by a sandy beach around 50 A.D. A core drilled near the Villepey pond attests to a marine environment during this period. For the first time, these data show a strong dissymmetry of the shoreline during the Roman period.

In this paper, we describe an exploratory analysis of the possibilities of combining least cost path analysis and network analysis techniques. Accessibility is a potentially important site location factor. So far, the cost paths. However, these methods do not provide direct information on the foci of movement. Starting from networks created from least cost paths, network analysis and space syntax were used to obtain additional information on the structural features of the network. It is concluded that both techniques can be used with least cost path-based networks, and will provide new insights into the characteristics of the network. For most applications however the space syntax measures that take the geographical dimension into account seem to be preferable to the simple network analysis measures used here.
