Local community feel. Fascinating and surprisingly a lot of exhibits and a lot to learn. About the local fishing community way of life and tools used. About King Carlos's extensive research in marine life.

Excellent on the history of the local fishing industry. Well worth an hour or two

Small but interesting. Exhibits well labeled in Portuguese and English

This is a small museum located in Cascais that brings a bit of the Cascais’ maritime history with costumes, tools, nets and boats. Hours: 10am-6pm Tue-Sun, free 1st Sun of month Price: adult/child €3/free

Cool small sea museum, very cheap tickets. 1 hour interesting visit

Worth it’s cost. Personally I liked it here, besides it’s totally family friendly. The museum isn’t that big, but you can totally spend about an hour here enjoying all the mammals around. :) Appreciate information in English they have here. Of course, I’d like to see more exclusive stuff regarding the royal family, hope they will add some new items in the future.

Interesting overview of Portugal's connection to the Sea.

A nice little museum with lots of information but not too much - great for spending 1-2 hours with kids

Nice small museum about the sea located in a historical building, both related to the last king of Portugal.

Nice place to know more about Cascais fishermen, sea research, sea and oceans. Excellent exhibition and interactive demos for kids.

a gem of an attraction!..historic, fun& informative... a must see in Caiscais

Great museum, well worth a visit. It is only free to residents, and they don’t take card. €3 adults and €1.5 children.

A good visit for kids, but for adults only it is a bit boring.

Small museum, nice information and also in accurate english. however it kind of smells.

An interesting museum about the sea including finds from local shipwrecks.

The museum is bigger than expected. Nice place to chill after hot weather.
