Orthodox chapel on site of plane crash

i am not sure about the building of whole churches, but in Greece we build a small iconostasi in sites where fatal car accidents happen.
you can see some here :

iconostasi these commemorate fire victims. you rarely see so many iconostasia together.

iconostasi 2

iconostasi 3


especially when young children or young adults are killed, relatives place at the iconostasi photos of the children, maybe a plate with some writings (poems or the date of death), and leave flowers.

the majority of them are small, have icons, and a vigil candle.

There's a Russian Orthodox Chapel at Dachau, the Concentration Camp from Nazi Germany. One of the large icons there show Christ freeing the prisoners from the camp:

hi Kalevalatar,

the cemetary (grave) is probably located closer to the family, while the iconostasi can be very far away from the family (if it was a car accident it can be in the national highway) so although there's a vigil candle in both, it might be difficult for relatives to visit the iconostasi.

at the grave a priest does trisagion (a prayer), but i am not aware if it's common practice to do the same to an iconostasi.

i remember a site where students in a school bus were killed in a very dangerous place at the national highway, i heard that their families gathered to pray a trisagion for their children souls the other year.

It definitely happens
