Hacker News上关于“秘鲁伟大的城市实验”的讨论总结如下: 这篇文章引发了关于游览秘鲁的讨论,评论者分享了他们的经历。一位在蜜月期间游览了Chan Chan的用户强烈推荐这个国家。其他人也谈到了安全问题,指出虽然需要常识,但在旅游区通常是安全的。一位用户提到在秘鲁比在巴西感觉更安全。 一些用户提供了旅行建议,例如入住旅馆,使用现金,并在旅游区保持谨慎。另一位用户反驳说,总是需要“保持警惕”反映了政府未能提供安全环境的失败,并将其与亚洲城市作了不利比较。 原文还引发了关于城市决定性特征的讨论,特别是城墙的必要性。一些人认为城墙是必不可少的,而另一些人则指出了世界其他地区,尤其是在穆斯林/奥斯曼世界中,无城墙城市的例子。

    Peru's Great Urban Experiment (2023) (archaeology.org)

    I've visited Chan Chan during my honeymoon last year, it's impressive! All Peru is impressive, north to south. Highly recommended!


    There is so many things to see in Peru. And so many things we dont know about the world.


    Great you visited it. One reads all these cautionary notices about traveling to Peru. What was your experience? Did you visit on a group tour? Would love to know more.


    I was there couple years ago. If you don't go to places you shouldn't, you are mostly Ok. I felt much safer in Peru than in Brazil for example. It is not europe or some parts of asia. But for central/south america it was farily safe. Not sure about some changes in the last years.


    Peru has had a lot of bad press but if you use your common sense you’ll be fine. I live in Lima, for example the tourist areas here have a high police presence and are safe.


    I felt kind of safe there, depends of a district. But I know personally a guy 1,9 meters, boxer, that got drunk and took a taxi, the guy drove him to darl alley where friends were waiting and took his stuff. So it is always about using your brain and a bit of luck. But that was more than 10 years ago. Maybe with uber, these situations are safer.


    I went there with my younger kids a few years ago. It was like visiting the USA only fewer guns and authoritarian people in uniforms everywhere, and don't drink the water out of the tap. Also maybe pay in cash everywhere since no one takes cards. Lima is big and like big cities everywhere be on your guard in touristy areas because a lot of people make a living there and not always through legal means.

    Hiking the Inca trail to Maccu Piccu and seeing the Nazca line in person though, worth it. Just stay in hostels and travel by bus. A bit of Spanish would help but we got by OK without it.



    > Lima is big and like big cities everywhere be on your guard in touristy areas because a lot of people make a living there and not always through legal means.

    Super weird to normalize urban violence.. as someone who lives in Asia.. this is a really messed up terrorized mindset. You don't need to walk around Shanghai, Singapore, Tokyo, Seoul or Bangkok and "be on your guard" .. ever.

    Your government(s) have just failed you in providing a safe environment to live



    It must be historical and also how cities are settled. South America has huge influx of uneducated, poor people into the cities. It is easy for them to get entangled in bad activities in the slums. Like Rio. Beautiful city and some government reforms pushed ex slaves into city with no prospect for life. and government forgot about them until there was a problem. And maybe there is different social net in Asia. Culture based on shame, more than power/status(?).


    Yes, Peru (and South America in general) can be fairly dangerous for people used to Europe or the US, but if you let you be guided by someone who knows where to go, it is a wonderful place. My wife herself is Peruvian but lived in Europe for her whole life so it was a new experience for her as well. We travelled on a tour planned by a travel agency ad-hoc for our honeymoon, so we were alone (not in a group) but we were escorted by private guides for all the travel, who organized both the transports and the touristic activities. Schedules were tight so it was challenging, but really rewarding! On top of the usual famous places like Machu Pichu I also greatly recommend the amazonian region. We went to a lodge on the Marañon river some kilometers from the source of the Amazon River and met local tribes (including one of the five last speakers of a disappearing local ancient language). Great memories for sure!


    Very interesting article, especially if you interested in how societies become organized and urbanized. Two fundamental requirements for a city, is a source of water, a centralized economy, such as a palace, that stores food and artifacts, and lastly be enclosed in walls. I am surprised that no such perimeter walls existed, although the palaces were surrounded by walls.


    If there is a stable peace then walls aren't so necessary, like during the Pax Romana many cities in safe parts of the Empire didn't have walls, or they had old walls built in more dangerous times and the city then expanded outside of these.


    I'm confused if you mean that a palace needs to have enclosing walls to count, or the whole city?


    Yes, who can think of Los Angeles without considering its massive and all-encompassing walls.


    It does have massive, and all encompassing walls. They aren't built like how we used to build defensive walls in history, those are obsolete. Instead they are lined with chainlink and razor wire, contain radar and other systems for across the horizon detection, have runways for aircraft, silos for ballistic missiles, magazines for gunships, missile carriers, submarines, satellites and other craft in outer space with classified capabilities, entire datacenters. It is one of the most well defended positions in human history.


    Right, the silo fields in North Dakota are obviously part of the great wall of Los Angeles. Ask any citizen of Fargo and they will confirm that they are indeed proud bricks in the great Angelino wall and renounce any claim to living in a city themselves.

    /s



    The absolutely are, though. Not just LA, of course, but for all American cities.


    It truly would not be a safe settlement without the great Angeline Walls keeping Los Gigantes out from the north.


    The two fundamental requirements for a city are:

    1) a source of water,

    2) a palace or other place to center an economy, and

    3) to be enclosed in walls.

    We know the last because we have yet to discover any traces of the walls of any unwalled cities.



    > and lastly be enclosed in walls

    This is mostly a Western-centric view, as there were lots and lots of cities in the Muslim/Ottoman world (just to give an example) with no walls encompassing them whatsoever.
