3D LiDAR model of Chichester Roman City Walls, in West Sussex, UK. The digital terrain model offers a view of the surrounding landscape without obstruction from foliage. Chichester was founded by the Romans in the 1st century CE. Constructed in the 3rd century CE, the walls enclosed an area of around 2.4 kilometres and featured defensive towers and gates. Four main Roman streets still define the shape of the city, and traces of the Roman forum, houses and public baths are visible in places.
