Laxtrapporna marks the site of the 1767 sawmill, Nya Mölla. Now, a waterfall here powers a hydroelectric plant, offering a serene setting for picnics and summer swims in the fish ladder. With convenient parking and bike access right up to the waterfall, it's an ideal starting point for Munka Möllestig, a scenic trail along the river.

The Western Wall is the only part remaining of Solomon's Temple, built in the 10th century BC and destroyed twice. Praying here carries a lot of meaning for Jewish believers, who mumble hymns and insert prayers written on small pieces of paper between the bricks — every visitor is allowed to partake. The Temple was said to contain the Ark of the Covenant, a biblical golden chest. Moreover, Jesus reportedly visited the Temple as a child and left an impression on the wise men inside with his knowledge of the Bible. There are separate entrances for men and women leading to different parts of the wall. Friday evenings are particularly crowded, as Jewish people celebrate the arrival of Shabbat, the day of rest. Bar Mitzvah ceremonies take place in the morning on Monday, Thursday and Saturday: it's a great time to visit, as the place comes alive with Jewish song and dance.
