Some of the offerings include, An Offering of Beauty by Evan McWilliams, Back to the Future: Ecclesiastical Art after Postmodernism by Dr. Janet Rutherford and Praise with Majesty and Reverence, written by a member of the Maronite Patriarchate of Antioch. Amongst the many book reviews available online is a review of Dr. Denis McNamara's book, Catholic Church Architecture and the Spirit of the Liturgy.
Rather than summarizing each of these, I will simply draw your attention to them for your own consideration and reading pleasure.
While Sacred Architecture does give a very liberal dose of its articles online, I would certainly encourage you to consider taking out a subscription (which costs but $9.50 USD per year). While only published twice per year, aside from the interesting articles, it always includes a number of beautiful colour reproductions of sacred architecture within, as well as an always interesting survey of news related to the world of sacred architecture -- something not available online to my knowledge.
It is an excellent periodical; one I am always delighted to receive in my mailbox.
Related to the matter of the photographic imagery found in the journal, I wished to point out the following two images found within the context of Dr. Rutherford's piece, "Back to the Future: Ecclesiastical Art after Postmodernism" which show work from the Beuron School.
