Santiago's must-sees are not a parade of glass towers and rooftop bars. This list covers three things: the churches the city built to last, a handful of buildings that carry the state's Historical Monument designation, and two places where Chile asks visitors to face its recent past. It opens on the Plaza de Armas, home of the Metropolitan Cathedral, and moves out to Peñalolén, where the Bahá'í House of Worship for the South American continent stands on Diagonal Las Torres. In between are an opera house dating from 1857, a TV tower from 1974, and a mosque in Ñuñoa. Skip the hop-on bus loop that treats all of this as scenery. These places reward a slower visitor who will step inside, read the site's own account, and accept that a few of them are not meant to be pleasant. If you want a highlights reel, look elsewhere. If you want to understand what Santiago keeps, protects, and remembers, this is the list.

1 Santiago Metropolitan Cathedral
Plaza de Armas, SantiagoA national monument facing the city's main square, where the plaza's bustle stops dead at the door
Dating from 1800 by Wikidata's count, the Santiago Metropolitan Cathedral anchors the Plaza de Armas. It is a national monument of Chile and holds the Historical Monument designation, so the state treats it as part of the country's inheritance and not merely as a parish church. Skip the quick photo from the far side of the square and go inside. You come here to walk out of the plaza's bustle into the hush of the nave and feel how sharply the two worlds divide at the threshold. It sits at roughly 33 degrees south and 70 west, and this is the square to plan your first day around. Start here and let the rest of this list fan out from it.

2 Torre Entel
20 Amunátegui, SantiagoSantiago's TV tower, the downtown landmark you steer by
A TV tower at 20 Amunátegui, Torre Entel has stood since 1974. Don't plan your day around getting inside; treat it as a compass instead, because once its silhouette is fixed in your head, it is the easiest way to work out where you are in the centre whenever a clear sightline opens up. The tower carries the telecom company's name, and its listed official site is Entel's own corporate page at informacioncorporativa.entel.cl, which is as plain a statement as you will get that this is a working mast first and a postcard second. Look up at it from the street at dusk and you will see why it made this list: the skyline reads more clearly with it than without it.

3 Bahá'í House of Worship for the South American continent
Diagonal Las Torres, PeñalolénThe Bahá'í faith's House of Worship for an entire continent, well off the downtown circuit
Out on Diagonal Las Torres in Peñalolén, the Bahá'í House of Worship for the South American continent sits far enough from the usual circuit that many itineraries never reach it. Don't make that mistake. Skip the urge to cram one more downtown church into the afternoon and come here instead, because this is the Bahá'í House of Worship for Peñalolén, Santiago, and its name says it plainly: one temple for a whole continent, which makes it a pilgrimage for the faith and an unusual find for everyone else. It is mapped at about 33 degrees south and 70 west. Check visiting arrangements on templo.bahai.cl before you set out, because the journey is the real commitment, not the visit.

4 Villa Grimaldi
A Historical Monument that asks for an unhurried afternoon of attention
From 10:00 to 18:00, Monday to Sunday, Villa Grimaldi opens its gates to anyone willing to make the trip. A national monument of Chile with Historical Monument status, it belongs on a must-see list for reasons that have nothing to do with beauty. Don't wedge it between a winery tour and dinner; give it a full afternoon, arrive well before the 18:00 close, and leave yourself time afterwards to sit with what you have seen. Read the site's own account at villagrimaldi.cl before you go, so you arrive knowing whose story this place tells and why the country chose to protect it.

5 Basilica of Lourdes
645 Lourdes, Quinta NormalA Quinta Normal basilica that presents itself first as a sanctuary
The Basilica of Lourdes at 645 Lourdes in Quinta Normal sits well away from the downtown churches most visitors stick to, and the name of its official site, santuariolourdeschile.cl, signals where its priorities lie: it is a church building in Quinta Normal that operates as a sanctuary first and a monument second. The locals understand the difference. Resist the tour-group instinct of ranking churches by age or grandeur, and come here to see a place in daily use. Pin the coordinates, roughly 33 degrees south, 70 west, before you leave the centre, and give your driver the street address rather than a translated name.

6 Municipal Theatre of Santiago
Agustinas 794An opera house from 1857, best seen from a seat with the house lights going down
Book a seat before you book dinner: the Municipal Theatre of Santiago at Agustinas 794 is an opera house and cultural centre meant to be seen from the stalls, not the pavement. It dates from 1857 and holds Historical Monument status, but the facade photograph is not worth stopping for. The building makes full sense with an audience settling in and the house lights going down. Check the programme at municipal.cl and take whatever is on, opera or otherwise; the occasion matters more than the bill. Dress up a little, arrive early, and let the evening move at its own pace.

7 As-Salam Mosque
A working mosque in Ñuñoa that widens the city's religious map
Street noise fades at the door of As-Salam Mosque, a mosque in Ñuñoa, Santiago that dates from 1989. It is a useful corrective to the assumption that every must-see here has to be Catholic and colonial; Santiago's faith map is wider than its cathedral square suggests, and the mosque sits at about 33 degrees south and 70 west. Treat it as a working place of worship rather than a sight: dress modestly, check prayer times before you go, and ask before taking photographs inside. Pair it with a slow walk around Ñuñoa afterwards and you will come away with a fuller picture of who lives in this city.

8 Votive Temple of Maipú
A national sanctuary whose name records a vow
The Votive Temple of Maipú, which Wikidata dates from 1818, deserves a half-day of its own. It is a national monument of Chile with Historical Monument status, and the word votive in its name is telling: this was conceived as an offering, a vow made good. The official site runs as santuarionacional.cl, presenting it as the country's national sanctuary, which gives you some sense of the weight behind the building before you arrive. Don't squeeze it in at the end of a long day; give it its own slot and arrive with energy. It is mapped at roughly 33 degrees south, 70 west. We'd check the sanctuary's site before going for anything that might change your timing.

9 Basílica del Corazón de María, Santiago de Chile
Zenteno, SantiagoA protected basilica on Zenteno with its own entry on the national monuments site
The Basílica del Corazón de María stands on Zenteno in Santiago, a national monument of Chile with Historical Monument status. The government's monuments site gives it its own page at monumentos.gob.cl; read that before you go and you will look at the building with sharper eyes. Avoid the reflex of saving your church visits for the cathedral alone. This is the kind of protected basilica that gets less attention, and it is better for the quiet. It is mapped at about 33 degrees south and 70 west; walk there rather than taking a cab, and look up as you arrive.

10 Iglesia de los Sacramentinos
1127 Avenida Santa Isabel, SantiagoA national-monument church on Avenida Santa Isabel, still run by its own community
The traffic hum fades as you reach the door at 1127 Avenida Santa Isabel, the address of the Iglesia de los Sacramentinos. It is a national monument of Chile with Historical Monument status, and it still runs its own website at sacramentinos.cl, a good sign that this is a living church rather than a protected shell. Skip the guidebook habit of treating every large church as interchangeable; give this one twenty minutes on its own terms. It is mapped at roughly 33 degrees south, 70 west. Come on a weekday morning, when the avenue is busy and the inside is not.

11 Londres 38
Londres 40 ex 38A Historical Monument that keeps its old street number as its name
The street number has changed to 40, but Londres 38 kept the old one as its name, so the address now reads Londres 40 ex 38. That small detail says a lot about a place that refuses to let its past be renumbered. It is a national monument of Chile with Historical Monument status, and Wikidata dates it to 2009. Don't come for the architecture. You come for what this address holds, and the site's own account at londres38.cl is where we'd read before arriving. Go alone or in a small group, keep your voice down, and give yourself time to walk afterwards.

12 Basílica del Salvador
A protected basilica worth more of your time than its low profile suggests
Give the Basílica del Salvador more of your time than its modest standing among visitors would lead you to expect: it sits in Santiago de Chile, dates from 1932 by Wikidata's count, and holds Historical Monument status. The checklist approach, tick off the cathedral and call Santiago's churches done, misses too much. It is mapped at about 33 degrees south and 70 west. Walk around the outside before you try the door, look at it from more than one corner, and expect to stay longer than you planned. It makes a fitting last stop for a list built on what the city chose to protect.
