Aðalstræti is Reykjavík's oldest street and lies at the heart of the small grid of streets that still bear echoes of its fishing village past. The name means Main Street, although it has its origins as a simple path, probably linking a farm at its southern end with the sea. That farm is thought to have been the home of Ingólfur Arnarson, the first Nordic settler in Iceland. As the town grew up around this area, , Aðalstræti became indeed its main street, and would have been lined with the homes of important residents, as well as the meeting house and the town’s main well, Ingólfsbrunnur (“Ingólfur’s well”), outside the present-day number 9.

The city’s oldest timber-house, Geysishúsið, is in this street at number 10 (see photo). It was built in 1762. Nearby, at the southern end of the street, is the Settlement Exhibition, which preserves the ruins of a 10th century Viking long house, along with objects and remains of human habitation believed to date from the 9th century settlement of Reykjavík.

The tall tower of the Hallgrimskirkja can be seen from all over Reykjavik.

The church is not an old one, as becomes clear when you get close to it. Its construction started in 1945 and was only completed in 1986. It was designed by the state architect Guðjón Samúelsson to imitate the basalt lava flows that are so typical of the Icelandic landscape.

The design might be considered controversial as it is not one that appeals to everyone, but I rather liked it. Inside the church is spacious and, unsurprisingly, modern in feel. There is an impressive organ, the biggest in Iceland – 15 metres tall, weighing 25 tons and with 5,275 pipes. It is a recent addition, dating from 1992.
