"박물관에 갑시다."

Translation: Let's go to the museum.

[MaskedPeach]

Apparently, you read "박물관" as "방물관". (as says Naver)

Yes, it's a rule: ㄱ+ㅁ --> ㅇ+ㅁ between syllables/letter blocks.

[Straw_Neige]

OK, so we add ㅂ시 to the verb to say "let's", is that right?

[JuniperGhi]

I accidentally spelled museum wrong, adding one extra letter, and I still got it wrong. It usually says I made a typo when I accidentally do this, but this time it didn't. Why did this only happen for this one?

博物館

[Fabiola_Mac]

But why is it 에 instead of 으로? If we're talking about going to a place, not a place you're already in.

[oee16]

에 marks a location/point of destination. (으)로 indicates direction.

박물관에 갑시다 = Let's go to the museum [point of destination = museum]

박물관으로 갑시다 = Let's head for the museum [move in the direction of the museum]
