Pagan Anglo-Saxons worshipped at a variety of different sites across their landscape, some of which were apparently specially built temples and others that were natural geographical features such as sacred trees, hilltops or wells. According to place name evidence, these sites of worship were known alternately as either "hearg" or as "wēoh". Most poems from before the Norman Conquest are steeped in pagan symbolism, and their integration into the new faith goes beyond the literary sources. Thus, as Lethbridge reminds us, "to say, 'this is a monument erected in Christian times and therefore the symbolism on it must be Christian,' is an unrealistic approach. The rites of the older faith, now regarded as superstition, are practised all over the country today. It did not mean that people were not Christian; but that they could see a lot of sense in the old beliefs also"
