Noarootsi church is the youngest fortification church in Estonia, built around 1500. It served the congregation of Swedes living on Estonia coast, but also held a defence function. Currently, it is one of the three churches in Estonia with plank roof. Most interesting artefacts inside the church are the baptising stone, baroque pulpit, limestone baroque epitaph to Minister Martin Winter.

The Peace Palace (Vredespaleis) is an administrative building and often called the seat of international law because it houses the International Court of Justice (which is the principal judicial body of the United Nations), the Permanent Court of Arbitration, the Hague Academy of International Law, and the extensive Peace Palace Library. In addition to hosting these institutions, the Palace is also a regular venue for special events in international policy and law. The Palace officially opened on 28 August 1913, and was originally built to provide a symbolic home for the Permanent Court of Arbitration, a court created to end war which was created by treaty at the 1899 Hague Peace Conference.
