Kopgalis Fortress


  • Kopgalis Fortress is one of Klaipėda’s most significant historical landmarks, located at the northernmost tip of the Curonian Spit, where the Baltic Sea meets the Dane River. Originally constructed in the 19th century by the Prussian military, the fortress was built as a coastal defense stronghold to protect the strategically vital port of Klaipėda. Over the years, it has undergone various modifications and played different roles, from a defensive fortification to a military barracks and, eventually, a cultural heritage site. Today, Kopgalis Fortress is home to the Lithuanian Sea Museum, making it an essential stop for history lovers and maritime enthusiasts.
  • The fortress itself is an impressive example of military architecture, featuring thick brick walls, underground tunnels, and artillery positions that once housed powerful cannons to defend against naval invasions. During the World Wars, Kopgalis Fortress was utilized by the German and Soviet forces for military purposes, adding another layer to its complex history. Despite suffering damage over the decades, significant restoration efforts have helped preserve its structure, allowing visitors to walk through its tunnels and explore its defensive ramparts with breathtaking views of the Baltic coastline.
  • Since 1979, Kopgalis Fortress has served as the site of the Lithuanian Sea Museum, which showcases a vast collection of maritime artifacts, including historical ships, navigation tools, fishing equipment, and exhibits on Lithuanian seafaring traditions. The museum also features engaging displays on marine biology, Baltic Sea ecosystems, and Klaipėda’s naval history, making it an educational experience for visitors of all ages. One of the highlights of the museum is its aquarium and dolphinarium, where guests can observe a variety of marine species and even watch interactive dolphin and sea lion performances.
  • A visit to Kopgalis Fortress offers a unique blend of military history, maritime heritage, and natural beauty. Whether you’re exploring its historic defenses, learning about Lithuania’s deep connection to the sea, or simply enjoying the scenic surroundings of the Curonian Spit, this fortress remains a must-see attraction in Klaipėda.
