My old pbase galleries are still up here:

"Miscellaneous" has a lot of development-related photos. The oldest I think are from around 2002/2003. Unfortunately in many cases the quality is quite poor and there are a lot of photos I don't have anymore. I remember taking pictures of the Bishop's Landing construction site for example, the construction of the hotel at Hollis and Salter, etc.
The first shots I put on SSP were back in 2001 or 2002 and were taken on film (it is weird to think that they're now 10 years old!). I haven't taken any photos much older than that. A few interesting ones I have are:
-View from Citadel looking North across Commons from 2001 (looks like the condo/apartment on the west side of Cunard and Agricola is under construction). Lots of new buildings are missing.
-A couple of views looking South that include Park Lane pre-Martello, taken just after the Garrison Watch building was built at the corner of Dresden Row and Sackville.
-YWCA on Hollis.
-Infirmary.
-Victoria Apartments at Hollis/Morris, which actually did not change much until very recently.
-Garden Crest construction site at the corner of Summer and Spring Garden.
It would be very interesting to assemble "then and now" pairs of pictures. Some corners of Halifax have changed a lot over the past decade! In a few more decades photos like the one of the Citadel Hotel above will be very interesting to some younger people who won't even remember that building.
