sentences:  By April 1852 the lower sections of the gates had been installed, decorated with a combination of elements from the interior balconies; four great panels of rope-work with central mermaid and trident figures identical to those inside.The two outer panels were fixed whilst the two centre sections rolled behind them on rails where they were hidden from sight while the Home was open for business.The iron-work of the lower gates, being on such a large scale, produced a solid, intimidating aspect compared with the much lighter appearance of the balcony railings.
