From the 1500s Hop was noble estate for the law speaker in Bergen and Gulen judicial districts. Several of the law speakers were of noble descent, such as Hans Hansen Lillienskiold and Niels Knagenhielm. The beautiful main building, still standing, was erected by the Bergen merchant Thomas Erichsen in 1793-95. He also established a magnificent garden with an 800 metres long linden avenue reaching down to the stone boathouse at Hop harbour.
Moster is mentioned as a church site already in the time of Olav Tryggvason. According to the sagas the king is supposed to have laid the foundations for the first church at Moster when he came there in 995. That building would have been a stave church - the church standing there today – a stone church with a nave and narrower, straight chancel – was probably founded around 1100. In 1874 a new church was built at Moster. Then the old church was bought by The Society for the Preservation of Norwegian Ancient Monuments, which is still the owner.
