I have been a frequent and regular visitor and resident in Tel Aviv. Tel Aviv remains the greatest collection of Modern Movement architecture I have ever seen. Although many, possibly most buildings, have been altered, the alterations are not of a permenant nature. The most common and nearly ubiquitous change is the addition of "treeseem", sliding louvered blinds enclosing the open air porches or negative spaces of the buildings. The renovations which have been ongoing for several years are remarkable. Many of the renovated buildings appear to be pristiine in condition. Those buildiings with contemporary additions are done so that a clear and obvious distinction remains between the old and the new. Tel Aviv is THE MUST SEE city for modernists.
