Numerous finds show that the settlement at Herdla goes back to prehistoric times, and the large estate at Herdla has enjoyed a central place in the nation’s history since High Middle Ages. As Ask, Herdla was part of the country estate Harald Hårfagre took over as he took command of the west of Norway.
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.
The grand farm Aga on the west side of Sørfjorden, came under protection in 1937, when the agricultural reform threatened to disperse the old clustered settlement. “Lagmannsstova”, named after the “lagmann” (law speaker) Sigurd Brynjulfsson, was already protected in 1924; one of the authentic profane wooden buildings from the Middle Ages still standing. All the same it is the farmyard itself that is the key cultural monument.
Well over 200 years ago, the priest Niels Hertzberg started making climate observations at the vicarage at Lofthus in Ullensvang. Hertzberg was active and ahead of his time in many fields, and had a great interest in natural science. Temperature and pressure were measured daily at the vicarage - often several times a day - with homemade instruments. The meteorological measurements started in December of 1797, and were carried out continuously until 1840, the year before he died.
