When construction actually began
No reliable event specific to 10 April 1942 has been verified. The Treblinka Museum dates the start of physical construction to the beginning of June 1942; Yad Vashem gives late May or early June. The surviving evidence separates preparatory decisions, surveying, contracting and building imperfectly, so no exact groundbreaking day is secure.
The preparations behind it are better documented: arrangements probably ordered during Himmler's 17 April visit to Warsaw, and a May agreement between Operation Reinhard leader Odilo Globocnik and the Führer Chancellery concerning the camp's construction.
Six weeks of forced construction
A special SS construction team under Richard Thomalla directed the project, with work performed by two German firms and forced laborers — Jewish workers from nearby ghettos and Polish prisoners from the Treblinka I penal labor camp, about two kilometres away. Nearby Jewish communities were forced to supply materials for the facility intended to murder them.
The site was chosen for concealment and rail access: a wooded rise beside an existing gravel-pit railway. The builders enclosed roughly 17 hectares behind a double, approximately 2.5-metre fence woven with pine and juniper branches, and built an access road, a rail siding, barracks, and a building containing three initial gas chambers.
From completion to killing
The Treblinka Museum dates completion of the initial construction phase to 11 July 1942. Twelve days later, on 23 July, the first deportation transport arrived from Warsaw and the killing began.

Date disputed. Sources disagree; the research places it at ~1942-06.
What the sources leave uncertain
- April 10 is not supported by the Treblinka Museum or Yad Vashem. The museum gives 'the beginning of June 1942'; Yad Vashem gives 'the end of May or beginning of June.'
- Because the surviving evidence distinguishes preparatory decisions, surveying, contracting, material deliveries, and physical construction imperfectly, a single exact groundbreaking day is not secure.
- The corrected date is therefore approximate, represented here as ~1942-06 rather than retaining the unsupported 1942-04-10.
