A grand Hall of Pillars was constructed to serve as an impressive entrance to the House of the Forest of Lebanon, acting as a lobby or gatehouse for the main building [מצודת דוד, רד״ק, אברבנאל, שטיינזלץ]. The hall measured fifty cubits in length and thirty cubits in width. The fifty-cubit length actually corresponded to the width of the main house itself; however, the larger dimension is always referred to as the length, while the shorter is designated as the width [רש״י, רלב״ג, אברבנאל]. While the exact height of the hall remains unstated, it is assumed to have matched either the height of the main house or the tall pillars it leaned against [רלב״ג, אברבנאל].
The precise placement and architectural design of this hall are viewed in several ways. The primary approach among commentators is that it stood directly at the front of the house, near the doorways and main pillars, functioning as a covered entrance featuring a dome-like roof [רד״ק, אברבנאל]. Conversely, other perspectives suggest different layouts. One view proposes that a tall hall was built entirely above the main house [רש״י], while another suggests it was an additional, second hall constructed in front of the primary one [מלבי״ם].
At the front of the hall's entrances stood additional pillars, likely made of cedar wood and firmly planted into the ground [מצודת דוד, רלב״ג]. Resting on top of these pillars was a massive, thick wooden beam [רש״י, רד״ק, אברבנאל, מלבי״ם]. This heavy beam served a crucial structural purpose, connecting the pillars together and stabilizing them to prevent any movement. It also contributed to the roofing, added decorative appeal, and helped form a protective partition [מצודת דוד, שטיינזלץ]. Alternatively, these pillars may have been erected as a second story on top of the lower pillars. In this arrangement, wooden walls were woven between them, and the thick beams were used to construct the ceiling of the upper chamber [רש״י].
