Learn Spanish (Latin America): ¿Dónde queda el museo?

We use dónde because we are asking about a fixed location ("where something is"). You would use adónde if you were asking about a destination or movement ("where to"), like in ¿Adónde vas? (Where are you going?).

I learned that está is used for locations. What does queda mean here?

You can absolutely say ¿Dónde está el museo? to mean "Where is the museum?" However, the verb quedar is also very common in Latin America for talking about the permanent, physical location of places like buildings, landmarks, or cities. Here, queda translates to "is located."

Why is there an accent mark on the 'o' in dónde?

In Spanish, question words like dónde, qué, and cómo always have a written accent mark when they are used to ask a question. This helps tell them apart from the same words when they are used in regular statements.

Could I change the word order and say ¿Dónde el museo queda?

It is much more natural to say ¿Dónde queda el museo? In Spanish questions, the verb (queda) almost always comes immediately after the question word (dónde), and the subject (el museo) is placed after the verb.
