This Is My Glasgow<p>The former Tradeston Telephone Exchange. Designed in a Neo-Baroque style, it was built around 1935. Due to changes in telecommunications technology, it became vacant in the 1970s, and despite a number of attempts to rejuvinate it over the years, it has lain pretty much abandoned and decaying ever since.</p><p><a href="https://mastodon.scot/tags/glasgow" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>glasgow</span></a> <a href="https://mastodon.scot/tags/architecture" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>architecture</span></a> <a href="https://mastodon.scot/tags/glasgowbuildings" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>glasgowbuildings</span></a> <a href="https://mastodon.scot/tags/telephoneexchange" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>telephoneexchange</span></a> <a href="https://mastodon.scot/tags/tradeston" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>tradeston</span></a></p>
