From Rorate Caeli:
This event, the consecration of this altar, actually took place in 2010 for Munich's Jugendkirche ("youth church"). More pictures of the event can be found here. The altar is not as light as it appears: it is made of galvanized bronze and weighs 160 kilos all in all.
To see more examples from Germany, the old version of Fides et Forma has a post with pictures of Archbishop Gerhard Müller consecrating five very "modern" altars as Bishop of Regensburg, all during the reign of Pope Benedict XVI, all in beautiful old Bavarian churches.
From France we have this blank-looking altar consecrated in May of this year for the 12th century Abbey of Leoncel, this monument to dissonance consecrated in 2011 for the 18th-century Sainte-Madeleine de Besançon, and this cramped little altar consecrated last year in the historical Église Sainte-Marguerite de Soppe-le-Haut. Want more? See this (from 2011), and this (the article doesn't say the year, but this was installed in the centuries-old Carmel of Angers in 2012), and this (the new altar, along with the new ambo and throne of the Gothic-style Cathedral of Nantes, consecrated in May of this year). And there are so many other examples on the Internet...
In neighboring Belgium, Archbishop Leonard of Malines-Brussels blessed a glass altar in 2012 in the splendid neoclassical (18th c.) Église Saints-Jean-et-Étienne-aux-Minimes in Brussels.
For examples from Italy, we have this cube altar consecrated only last month for a neoclassical church, a new asymmetrically designed altar consecrated in August this year for an 18th century church in Trent (!), and yet another cube altar of rough stone consecrated in December last year for the 16th-century parochial church of Montorfano.
The Gesù in Rome was not spared. This banality was installed only a couple of years ago, when Benedict XVI was Pope.
Rorate has other posts on this theme.
These aberrations can and will continue, as these are but symptoms of the profound dislocation of the sacred liturgy of the Roman Rite. This dislocation cannot be set right either by purely voluntary movements for the promotion of the sacred from among the clergy and the laity or by the "good example" and "encouraging words" of any Supreme Pontiff.
And the "Liturgical Art and Sacred Music Commission" that was supposed to have been set up in the Congregation for Divine Worship late in 2011? No one seems to have heard of it after its creation was announced... Has it already joined the long list of aborted liturgical projects from the last two pontificates?
