Dong Xuan Market, at the northern edge of Hanoi’s Old Quarter is the city’s oldest market, originally built in 1889. However, in 1994 a fire destroyed much of the original building.
The market sells everything from dried mushroom and seafood to clothing, cloth, housewares, electronics, fresh produce and more. The market area sprawls down the street from the massive market building.
I walked up there this morning to have a look around and to buy some rice paper for fresh rolls to bring home.
I was amazed st the size of the sticks of cinnamon – close to 3 feet high – being sold. The odor was remarkable when I passed heaps of dried wood-ear mushrooms, and dried shrimp.
The aisles are tight and the whole place is a little overwhelming. If you shop here, negotiation is expected and the vendors are experts.

Really like the market pictures. Now i know why they call them wood ear mushrooms….A bit surprising for me was that this seemed a combo market, selling not just food, but clothing. Markets i had been to some centuries past were pretty much all single purpose. But yes, your photos are bringing back memories of the sights and smells of these places.
This place had a wet market, dry foods, clothing, utrnsils + food stalls. Tons of stuff, narrow aisles, and 3 floors. The place is massive plus there is a street market all around it.
