What's a post office like in your city? Vanuatu is a small island country in the South Pacific. There is an underwater post office. It is about 50 meters off the coast of Vanuatu.
The post office looks like a big can (罐头). It opened in 2003. It makes it possible for visitors to send postcards back home from under the sea. It's only open for one hour every day. The postcards and the stamps arewaterproof(防水的).
Now it's one of the busiest post offices for postcards in the world. Visitors from around the world want to experience the underwater post office. "Every week, hundreds of visitors post their postcards here," Vira Timbaci says.
Timbaci is in control of the underwater post office. It's his job to make sure that the postcards are collected on time at 3 pm each day. Sometimes he asks greatdivers(潜水员) for help. "Swimming to the post office is a great way to see the sea life," Timbaci says. "It's really beautiful here."
In the years since its opening, there are several other underwater post offices. For example, there is one in Malaysia at adepth(深) of 40 meters. It's the deepest in the world so far. But the one in Vanuatu will go down in history as the first of its kind.
