Buenos Aires Herald 
It’s almost Halloween and while it may be strictly coincidence that Buenos Aires city is hosting an event featuring old fossils and tombs this weekend, we’re gonna milk it for all it’s worth.
You should also get your tickets for some of the most iconic horror films on the big screen — from Psycho to Evil Dead — and indulge in more popcorn than your doctor would advise.
Without further ado, here’s our Herald recommendations to make this weekend a little scarier than normal (and not just because of the economy).
Thursday 24 — 5 p.m. to 9 p.m.
Arenales and Juncal, inbetween Cerrito and Montevideo
Free entry
This urban festival of the Arenales District draws a crowd — there were more than 10,000 people attending last year. It’s one night only, and the event is a you-have-to-be-there-to-get-it kind of thing, but we’re going to try our best to describe it, but bear with us because things are going to get kind of artsy.
Tendencia Arenales is essentially an enormous outdoor design festival that takes over the streets and showcases collaborations of more than 60 installations created by Buenos Aires’ best artists and designers. It’s a creative hub that uses decoration, lighting, exhibits, objects, clothing, and whatever else you can imagine to convey a theme.
This year’s theme is “The Weave,” and there’s a particular focus on the interconnectedness of lighting and how it transforms a space. You can expect to see circus aesthetics, sound artists, a construction site turned into art, and lots of nature-themed works from jungle to botanical, to a vegetable chimpanzee, to a waterfall of chairs.
Saturday 26 and Sunday 27 — 10 a.m. to 2 p.m. and 3 p.m. to 7 p.m.
Various locations across the city
Free entry
This internationally known architecture and urbanism event opens doors across the city to 120 areas with architectural, heritage, and cultural value. The open house includes spaces that are typically closed to the public as well.
It’s part of the Open House Worldwide event, where 55 cities across the world welcome the public to view iconic architectural spaces. The last time Buenos Aires participated in the event, it drew more than 60,000 visits.
There’s an online map and catalog of all participating spaces, some of which require pre-registration. Featured locations include the dome of the Bencich Building (a historical heritage site), as well as the Macro Tower, the National Library, the Paseo la Plaza, the IBM Building, and Barrio Parque Los Andes.
The event also includes other activities such as a photography contest, as well as walking and cycling tours.

Horror classics on the big screen
Thursday 24 through Wednesday 30
Halloween is right around the corner, which is the perfect excuse to catch up on some classic horror films on the big screen, courtesy of the Cinepolis chain theaters, which scheduled a horror program called Into the Beyond. The selection of films by some of the finest horror directors in film history will play throughout the weekend in Cinepolis theaters across the country.
From Alfred Hitchcock’s all-time classics Psycho and The Birds to 1990s iconic villain Freddy Krueger on A Nightmare on Elm Street. Brian de Palma’s adaptation of Stephen King’s novel Carrie and Roman Polanski’s Rosemary’s Baby are also in the mix, together with some 1980s cult classics like Sam Raimi’s Evil Dead and Tobe Hooper’s Poltergeist, co-written (and some say also directed) by none other than Steven Spielberg.
Agenda de cine has the hours for each film in each theater. Tickets can be purchased at the Cinepolis website.
