Plush 18th century mansion at the north edge of Inverkip. It's hired out as a wedding venue (sleeps 20) but doesn't operate as a hotel or restaurant or do tours. In the grounds is its predecessor, a ruined 15th century tower house. You'll have to be content with glimpses of the exterior of both as you drive past on A78.
Ardgowan House, Castle & Gardens is a privately owned late 18th-century mansion on the Firth of Clyde near Inverkip, Scotland. Ardgowan is located in Inverclyde, in the former county of Renfrewshire. The Ardgowan Estate has been held by the Stewart family since the early 15th century: towards the end of that century, their tower house Ardgowan Castle was built within the site of the previous Inverkip Castle fortress. The present house was erected in 1797 and completed in 1801 from designs by Cairncross. It is the seat of the Shaw Stewart baronets, currently Sir Ludovic Houston Shaw Stewart, 12th Baronet of Greenock and Blackhall.

This was built in 1805 in pink sandstone. A hundred yards southeast on Millhouse Road, the old cemetery is on the site of the medieval church; some of its stone was re-used in the Shaw-Stewart mausoleum, now derelict. People from Greenock had to walk six miles each way to attend here until in 1859 they got their own church.
