Another notable detail about this building is the drain. This runs obliquely from the court under the north guardroom, through the bottom of the tower. and out to the moat. It was massively built of large stones well  embedded in the strong mortar. It flushed the foot of the two shafts that descended from the upper floor garderobe of the tower, and then it passed out through a low archway at the foot of the tower and down into the moat. It must be remembered that, before there was a lock, the moat was filled and almost emptied at every spring-tide, so that tolerably good drainage was thus obtained.
   It should perhaps here be added that Kilburne (p.12) states that Penchester built "a faire Tower called Solomon’s Tower," and as Solomon’s Tower in its upper part was built in exactly the same style as the Penchester lodgings, it is to be concluded that if Penchester built the one he also built the other. Unfortunately it is likewise stated that the gate-house was built by Penchester’s successor Henry de Cobham. For several reasons it is impossible to accept this statement without reserve. To begin with, the gate-house is part of the Avelina

manor-house. Then, as far as its embattlement and elevation are concerned, the work is of the same kind and date as that of the ground floor of Solomon’s tower, which must have been earlier than the upper floors. Lastly, the gate-house seems to have been almost it not quite the first thing taken in hand when the restoration was begun, so that if Penchester built the tower he embattled the gate-house. It used to trouble me because I could find no castle gate-house of the time of Edward I. at all resembling this one.*  Its flanking towers are so weak and slender and have so little salience. It was only when I realised that the lower part of it might be really nothing more than the gateway of an unfortified manor-house of the end of the twelfth century that the difficulty seemed to be overcome.† (Plan No.3)
  * That at Lewes comes closest to it.
