Sant'Agostino Vescovo a Stagni di Ostia is a 21st century parish "church" at Via Giuseppe Micali 213 which is in the suburb of Stagni di Ostia to the south-east of Ostia Antica and part of the zone named after the latter.
In this street used to be a late 20th century dependent chapel of the parish of Sant'Aurea a Ostia Antica, called the Cappella dei Beatudini. This had an unusual dedication, to the Beatitudes uttered by Christ in the Gospel of Matthew.
However, in 2012 the new parish of Sant'Agostino Vescovo was founded, and took over the chapel as its temporary place of worship. This is now one of four parishes in the Suburbican Diocese of Ostia.
The original edifice must have been completely unsuitable, because in the same year the parish replaced it with a large tent or marquee (!).
The original tent had to be replaced with a new one in 2015. After understandable complaints, the Vicariate of Rome arranged in 2016 to provide a temporary structure such as a prefabricated hut.
Tragically, there were problems with the project for a permanent church that arose in 2016. Firstly, an ancient cistern was found on the proposed site which means further archaeological investigation. Secondly, the parish is in a queue for funds to build, and apparently the local parish of San Vincenzo de’ Paoli a Lido di Ostia has priority. Thirdly, and most seriously, the site is a drained marsh containing peat. This has been "spontaneously" combusting, and until this problem is solved the site cannot be built on.
Look for a white marquee on the west side of the street (this might have been replaced by a hut already as at August 2016).
The priest's house and parish centre is at Via Giuseppe Micali 21, to the south.
Permanent church Edit
The site of the proposed church of Sant'Agostino Vescovo is a scruffy field at the junction between the Via Giuseppe Micali and the Via Federico Bazzini.
The parish website states that Mass is celebrated:
Tuesdays 7:20, Wednesdays to Saturdays 18:00, Sundays and Solemnities 10:00.
