The old and new near Temple Square

SALT LAKE CITY — The log cabin, all of one story high, sits across from Temple Square between the Family History Library and the Church History Museum on West Temple. Built in 1847, it is the oldest man-made residence in the Salt Lake Valley.

Half a block away, the 30-story Promontory Condominium building sits on the corner of West Temple and South Temple, also across from Temple Square. Built as part of the soon-to-be-completed City Creek project, it is the valley's newest man-made residence.

The 164 years between the one development and the other tells the story of progress since the Mormon pioneers became the first white settlers to put down permanent roots in the valley.

OK, some things never change.

Something else that hasn't changed is the marketing approach. Both the old log cabin and the new condominiums are part of projects organized by The Church of Jesus Christ of Latter-day Saints to take care of the growing number of settlers coming to the valley.

No sooner had the first group of pioneers arrived in July of 1847 than Mormon leader Brigham Young ordered the building of a fort and numerous houses to provide for the hundreds of immigrants en route along the trail.

Some of the houses were made of adobe — none of which remain — and others of wood, two of which remain to this day.

One of them is the log cabin on display between the library and museum.

It was as high-end as they came 164 years ago — equivalent to the penthouses in the Promontory today.
