In the summer, Hoglands Park comes alive with a plethora of events, including lively flea markets, invigorating workout sessions, and more.

State Theater Altenburg was built in 1869 and was once the Royal Theatre. It is well worth a look inside as it has a beautiful historical interior. Approximately 165,000 people visit the theatre annually.

The building of Fredrik's church started in 1720 after drawings from the most famous architect at that point in Sweden, Nicodemus Tessin the Younger. In the spring of 2018, the church was reinvented after extensive renovation. The church is now one of the most modern in Sweden.

Portland is home to the nation's largest wooded urban park—Forest Park. A short hike in, and you'll find it hard to believe that civilization is just steps away. With 70 miles of trails winding through the forest and offering views of the Willamette River, you'll often have nature all to yourself. However, you're also likely to run into locals jogging or walking their dogs—expect to be greeted with a friendly "hello." If you have the time, hike up to Pittock Mansion, a stunning French Renaissance-style château that once belonged to Henry Pittock, a prominent publisher and businessman. Today, the mansion serves as a historic house museum open to visitors, offering panoramic views of the city. Another popular destination within Forest Park is the so-called "Witch's Castle"—the moss-covered ruins of an abandoned stone house. Despite its eerie name, there’s no record of witchcraft here. However, legend has it that its original inhabitant was the first person in Oregon to be sentenced to execution for murder in 1859.
