&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Harlem Valley State Hospital&amp;#039;&amp;#039;&amp;#039; was a psychiatric hospital complex in Wingdale, Dutchess County, New York, United States. It was operational from 1924 until its closure in 1994. Following its closure, the property was abandoned for many years and has only recently begun to be redeveloped.&lt;br /&gt;
&lt;br /&gt;
== History ==&lt;br /&gt;
The &amp;#039;&amp;#039;&amp;#039;Harlem Valley State Hospital&amp;#039;&amp;#039;&amp;#039; was established in 1924 as the Harlem Valley Division of the New York State Hospital. It was built on the grounds of the former Wingdale Military Academy. The hospital was designed to be a self-sufficient community, with its own power plant, farm, bakery, laundry, water supply, and sewage treatment plant.&lt;br /&gt;
&lt;br /&gt;
In the 1950s, the hospital was at its peak, housing over 5,000 patients. However, by the 1970s, the population had significantly decreased due to changes in the treatment of mental illness and the move towards deinstitutionalization.&lt;br /&gt;
&lt;br /&gt;
The hospital officially closed in 1994 and the property was left abandoned for many years. In recent years, there have been efforts to redevelop the property into a mixed-use community.&lt;br /&gt;
&lt;br /&gt;
== Architecture ==&lt;br /&gt;
The architecture of the &amp;#039;&amp;#039;&amp;#039;Harlem Valley State Hospital&amp;#039;&amp;#039;&amp;#039; is notable for its Georgian Revival style. The buildings were designed by the architectural firm of Walker &amp;amp; Gillette and are characterized by their red brick exteriors and white trim.&lt;br /&gt;
&lt;br /&gt;
== Redevelopment ==&lt;br /&gt;
In 2013, the property was purchased by the Olivet Management LLC, which plans to redevelop the site into the Olivet Center, a mixed-use community that will include educational, commercial, and residential uses.&lt;br /&gt;
