Worst place i have ever been

To be honest, it was very difficult for me to decide which was the worst place I have ever been, since I associate a bad place with issues of experiences and people, therefore remembering a bad place is not very pleasant for me because of multiple factors.
 Therefore in this post I will make reference to the place that I liked the least geographically, therefore I will only talk about aesthetic issues.
I do not remember any place that I have completely disliked for its geography, since if I travel somewhere it is to get to know and enrich myself with the culture of the site I am going to, but if I had to choose somewhere, I think it would be the city of Santa Cruz, sixth region, Chile.
Santa Cruz is a city and commune of Chile of the Province of Colchagua, in the Libertador General Bernardo O'Higgins Region, it has a temperate climate and within its tourist attractions are the vineyards, casino and Museum.
My father lived in this place for a short period of time, so when I was a child I visited this city regularly, I remember it as a dirty city with dangerous streets as well as very dark (which is found in any city), no I liked that everything was concentrated in a single point, since after walking the main street there was not much to see but ghettos, licore store, etc.
Although I must admit that I really liked going to the Main square for ice cream, visiting the museum that was close to the city center and the climate that lived in autumn and winter times were my favorites, despite the fact that the city I did not like it in its entirety, there were places that comforted me and I remember with affection.
