The western hemisphere isn't just the Americas. It includes half of europe...

There are quite a few people in the western hemisphere that don't even bat an eye when they walk past a 1000 year old building on their way to work every day.

For me the oldest building is just a random house from the 13 century.

The oldest building in/around Vienna is believed to be the Roman stone quarry in Leithaprodersdorf. It dates back to the Roman era, around 43 AD.

The oldest continuously inhabited building in Vienna is generally considered to be the Griechenbeisl, a historic restaurant located in the Innere Stadt district. It has been in operation since the 15th century.

I live in a young city, so its from 1407.

LAFITTE'S BLACKSMITH SHOP BAR, circa 1730

Surprise surprise, it's a church. Riddarholmen Church built in the 13th century.

Well there's a park with some ruins from the Roman occupation, which founded this settlement in 79AD. If you count them, that's 1945 years... if not, apparently there are some churches between 800 and 900 years old that still contains some parts of the original Norman construction, although they have been altered since

First or second century for the Roman baths. They're not in a great state though.

The student dorm I lived in was built as a monastery in 1491.
My current home town still has a guard tower built by the Romans.

I actually don't know. The area I now live in was partially wiped out by the tsunami in 2011 closer to the coast. We definitely have some buildings that are a few hundred years old that are still in use. Different parts of Japan have older, but it's almost always a Ship of Theseus sort of situation.

If you're talking white people, technically cooks cottage (built 30 years before the first fleet) but it was brought over and reassembled in the 1930's lol

Indigenous, probably the eel traps / farming system. That's 9,000 years old iirc

I live around the Yorkshire moors. There are dry stone walls up there which are up to 600 years old. I love walking up in the hills and thinking about that.

I live in Athens, and the oldest home still standing is about 500 years old (start of 16th century)

It was built in the 1820s

Early 1800's. I grew up in a house that was built in 1905.

The first Roman fort on the site of the castle was likely built around 55AD.

Had to look it up, but "most probably" built between AD 1000–1050. Love that it's old enough that we're not entirely sure...

Probably less than 100 years, I live in New Zealand....

1130, St Margarets Chapel.

The oldest extant building is circa 1832, so ~192 years old - not much compared to some places but doing well for an Australian building.

The oldest building near where I live was believed to be built in 1640.

Domtrapphuset, the cathedral staircase house, built sometime between 1280 and 1330 AD. The cathedral the staircase (currently) leads to was finished in 1435.

Nice trick to make ppl revel city they live in and possibly most of these ppl walk past it on semi regular basis so......

I think it is an old church from around 1100. The oldest residential house is much younger, about 1550.

I believe the first building here was contracted around 1920-40

I used to live in Regensburg, one of the northernmost Roman garrisons. So, the oldest remaining building (stone wall) is almost 2000 years old.

Weve got Roman era ruins I think, but I cant find any info on the oldest standing building. Probably from the 13th-14th century.

It was built in the early 12th century.

We have a church in Berlin that was built in 1220-1230

The tower of the old church was build around 1150, The rest of the church was build about 250 years ago.

Bremen Cathedral's oldest part is from 1044, but there was a wooden church structure there in 789 until it was completely burned down by raiding Saxons.

My grandma has a house, where a part of it was built by the romans

There's some debate on the age of the old parish church where I live. It was either built on the 7th century or 1078

Spanish mission church 1782

Skara brae. 3150 bc

142 years.

I live in the countryside so there ain't a lot...

Excluding ruins, 11XX. The exact dates aren't really known

I think the oldest building would be the castle that eas first officially mentioned in 1004 AD and the first parts of the castle were built way before that.

1310 it's a small house (max. 10m wide) in the town centre. Today it's part of the library of the University hosting different exhibitions. It's called Günter Grass Archiv in Göttingen, Germany.

Smederevo Fortress - 1428.

Used to live in an old house that was already in official documents since the revolution. So not too bad. Walls were so thick...

Most sources suggest 1100s

I lived "close" to Siem Reap and the oldest building is 900 year olds (Angkor Wat)

I'm not sure if it's THE oldest one, but Aarhus Cathedral is quite old, having elements from all the way back from the 1100s.

Still young compared to the city itself, though: Aarhus was originally founded in the 700s

Probably the 1840s in use. Ruins probably go back to the 13th century or thereabouts but they are no longer buildings..
