The king’s estates were an important base for the early power of the king. In the subsistence economy of those times it was easier to move people than goods. The king and his court moved from one king’s estate to another and benefited from the supplies provided for them until they were used up. The system also allowed a way of exercising control. When the king was absent an estate manager ruled in his place.
Following the battle in Hafrsfjord Harald Hårfagre acquired many estates that had belonged to his opponents. Alrekstad is certain to have been one of these estates and a chieftain’s seats wherefrom the old chieftain clan was evicted.
Snorre mentions Alrekstad as one of the five estates where Harald Hårfagre spent most of his time on his later years. And this is where Håkon the Good wished to go when he received the fatal wound in the battle of Fitjar in 961. Eirik’s sons also spent a lot of time at Alrekstad. But then we hear little of it until the time of King Sverre in the 1180s. After Bjørgvin was founded and Øystein Magnusson had a new king’s estate built at Holmen, to the east of the entrance to Vågen, Alrekstad was reduced to a subsidiary-farm. But as late as in 1226 there are accounts that Håkon Håkonsson used to ride to Alrekstad on Sundays. In the 1200s a church was built there. In 1277 Magnus Lagabøte donated Årstad to Nonneseter monastery. When the monastic system was dissolved in the 1500s, Vincents Lunge took charge of the property, which was included into the noble estate of Lungegården. Årstad estate was partitioned off as a recreational place for the bourgeoisie and in the first years of the 1800s, it was divided into several smaller recreational and separate properties. The town expansion in 1915 laid the basis for continued partitioning and development of land.
