Nedre Helland- Sand Quarries
The three spades in the municipal coat of arms for Modalen are sand spades. Sand quarrying has brought income and employment. As much as 70,000-80,0000 tonnes of sand and gravel left the municipality each year since the turn of the millennium, to be used as cementing sand. Why is Modalen endowed with so much sand?

Bakko
Everyone knows the famous painting by Tidemand & Gude “Brudeferden i Hardanger” (The Wedding Party in Hardanger) one of the great icons in the National Gallery. Some have, in a humorous lack of respect for this masterpiece linked the concept of “bride’s passage” to another pictorial presentation in Hardanger. This is found on the farm Bakko in Herand, carved in the rock by an unknown artist around 3,000 years ago.

Hæreid- geology
The Eidfjord terrace is a gigantic ridge that reaches up more than one hundred metres from the city centre in Eidfjord. It serves as a powerful natural monument left behind by the ice when it retreated.
