There's a small museum where you can learn how the local (Minnan-style) traditional houses are built.
A nice beach is a 5-10 min walk from the village.
One of Kinmen's 7 National Park villages, Oucuo has many traditional houses.
Introduction
If you want to combine beachcombing, an atmospheric stroll around a national park village and a museum, Oucuo is a good choice. Stay a night or two in one of the several lovely traditional house bed and breakfasts so you don't have to rush!
Typical of villages on this side of the island, Oucuo has a pond. It would have been built early in the village's life for 3 main purposes: feng shui, fire prevention and heat control.
Near the Ouyang Jhongyuan western-style building is the small Minnan architecture museum. Open daily except the Chinese New Year's Eve from 8:30am to 5pm, like almost all other Kinmen attractions, it's free. As soon as you step in, you'll notice the wonderful smell of camphor, the wood that's been used in traditional Kinmen house construction for centuries.
As you walk around, notice that many traditional houses' rooftops have a flat section. These were originally used to dry things harvested from the nearby sea. Fishing is no longer the main source of income for Oucuo villagers, but the sea is still there to enjoy, of course.
It only takes about 10 min to walk down to the beach. If it's low tide, be on the lookout for the half-buried tank in the sand.
